SME Annual Meeting 2019, Denver: mineral processing aspects

Last year's Annual SME Meeting in Minneapolis was a fairly low-key SME event, with 5083 delegates. Many people forsook Minneapolis for various reasons, but last year I felt that the mining industry was waking from its long slumber, so that we might expect a record turnout this year in Denver, the home of the SME.  I may have been a little premature, however, as the prices of base metals over the past 12 months attests (source InfoMine).
In 2017 there were 6300 delegates in Denver and in 2015 a record 7800. I looked forward to a larger than usual mineral processing presence this year due to the associated International Symposium to celebrate the 90th birthday of Prof. Douglas Fuerstenau. Because of this I did have a bit of an agenda this time, but for the most part I just wandered round the huge convention centre and exhibition, bumping into whoever appeared on the horizon.
It is impossible for an individual to produce a comprehensive report on an SME Annual Meeting, so the following is my diary of this major international minerals industry networking event, which took place February 24th to 27th at the Colorado Convention Centre, merely random snapshots of the many things taking place.
 
Sunday February 24th
Although various courses and committee meetings have been taking place since yesterday morning, the SME Meeting really began in earnest late afternoon today, when the exhibition hall was opened for a couple of hours. First impressions were encouraging, as there seems to be more people wandering around the huge number of booths than on previous Sunday afternoons.
Although Prof. Alban Lynch has been involved with hydrocyclones for very many years, in his conversation with me he said that "the way they are used now is an absolute nonsense, with circulating loads in some cases of well above 200%. The future is high frequency screens.....it is very clear that these screens are so much better than hydrocyclones."
By classifying by size-only, screens, compared to hydrocyclones, give a sharper separation with multidensity feeds and reduce overgrinding of the dense minerals. Derrick Corporation is the leader in this field and will be sponsoring an MEI Conference for the first time at Comminution '20, so it was good to drop by their booth to meet the USA team.

Canadian company Starkey & Associates is also a Comminution '20 sponsor, and John Starkey and his colleague, Spencer Reeves, are familiar faces at SME Meetings. Starkey & Associates Inc. is well known in the minerals industry, being a world leader in SAG mill design. Sacré-Davey Engineering is perhaps not so well known, the company having a high profile in mine design, but last year Sacré-Davey announced the expansion of its engineering and project management services by joining forces with Starkey & Associates, the Sacré-Davey team from Toronto moving to the Starkey & Associates Offices in Oakville, with John Starkey heading the office group as Chief Metallurgist for Sacré-Davey Engineering. I was pleased to call in at their booth to be introduced to Sacré-Davey representatives Alan Humber and James Scobbie, who were talking to Steven Bergounhon, of Lincoln Strategic, Canada.

Nice to catch up with 5 delegates from UK, who were on the same BA flight as me yesterday. International Mining is a media partner for all MEI Conferences, and editor Paul Moore and his colleague Phil Playle are regulars at SME. This year they were joined for the first time by fellow editor Daniel Gleeson. I photographed them in the International Mining booth with Carly Leonida and Mike O'Driscoll.
Carly is currently Editor-in-Chief of Mining Magazine, but is leaving in April to go solo as a free-lance mining journalist. I look forward to following her progress on her blog, The Intelligent Miner.  
Mike O’Driscoll was former Editor, then Global Head of Research, at Industrial Minerals magazine, and 4 years ago he and Ismene Clarke, former Head of Sales, at Industrial Minerals magazine, launched IMFORMED, a new source of information, research, and networking events for the industrial minerals business, which includes mineral processing as a major sector. Very much like MEI, they also organise international conferences and MEI is pleased to have entered into a collaborative media partnership with IMFORMED, where we actively promote the respective conferences.
Mike, Carly, Daniel, Paul and Phil
Moving on, I was lucky to catch the Eriez team. Long time Eriez veteran, Jose Marin (3rd right) was in attendance and showcasing Eriez’ high-gradient dry vibrating magnetic filters, which are used extensively throughout the industry to generate high-purity mineral products such as silica or lithium. Also Mike Mankosa (2nd left) and Jaisen Kohmuench (left) were present and discussing the successful deployment of EriezStackCell flotation technology into the non-coal mineral markets. Recently, a full-scale StackCell was installed in Western Australia for the recovery of nickel while another unit will be commissioned later this year for the recovery of rare earths. I look forward to hearing more on this in Cape Town in November, as Eriez Flotation Division is a sponsor of Flotation '19.
It was great to hear that Jaisen, Senior Director of Asia-Pacific Operations and Strategy, will be presented with the Frank F. Aplan Award at the SME banquet on Wednesday. Established in 1989, the Frank F. Aplan Award recognizes engineering or scientific contributions that further the understanding of the technology of coal and/or minerals engineering. According to SME Executive Director David L. Kanagy, Jaisen was selected as the 2018 recipient of this prestigious award based, in part, on his exceptional contributions to applied research, engineering development and commercial deployment of advanced flotation technologies.

Finally, on leaving the hall, I was pleased to be greeted by 5 delegates from the China University of Mining & Technology.
 
Monday February 25th
Judging by the long queue at Registration this morning, this could well be a record attendance this year, and the exhibition area was also a hive of activity.
Many of the exhibitors have large teams this year, including Clariant, one of the sponsors of Flotation '19. Clariant has developed HOSTAFLOT collectors, as alternatives to conventional xanthates, with safer handling and disposal, as they are delivered in bulk liquid form, eliminating the need to dispose of contaminated packaging.
It was great to spot Cyril O'Connor, President of the International Mineral Processing Council (IMPC), who was with President-Elect Ralph Holmes, of CSIRO, Australia, and Janine Herzig, President of the AusIMM, and one of only two women to ever be AusIMM President since its formation in 1893. Ralph takes over from Cyril at next year's IMPC Congress in Cape Town.

I then had a quick chat with Steve Fiscor, Publisher and Editor-in-Chief of Engineering & Mining Journal, and Regional Sales Manager Vic Matteucci.

It's always good to call in at the RSG Inc booth, to talk to my old friend and fellow northerner Chris Martin, who was with Chris Bean of The Quartz Corp, USA.
Chris's RSG Inc is an Alabama based manufacturer of milling and classification equipment, which closed 2018 with record sales. Projects include ultrafine calcium carbonate, fly ash, zinc metal powder and wet quartz milling in a 90kW wet ball mill rated for 5 tph at 150 microns. Chis tells me that 2019 has started well, with orders for hydrated lime, kaolin clay and fly ash ultrafine products.

Nouryon may be an unfamiliar name, but the well-known former AkzoNobel Specialty Chemicals was relaunched as Nouryon a few months ago. The move follows the acquisition of the business by The Carlyle Group and marks the company’s transition to becoming an independent, global specialty chemicals leader. We are pleased to have Nouryon as a sponsor of Flotation '19, and I called by their booth, where representatives were talking to Joshua Werner (3rd left) of the University of Kentucky, Osvaldo Bascur, of OSIsoft, USA and Hamid Manouchehri, of Sandvik, Sweden.
FLSmidth, a regular sponsor of MEI Conferences, recently entered into an agreement with AuTec Innovative Extractive Solutions, a subsidiary of Barrick Gold Corporation, for the purchase of the hydrometallurgical and mineral processing capabilities of AuTech by FLSmidth (MEI Online). Peter Flanagan of FLSmidth made a special announcement and presentation from the FLSmidth stand, aided by his colleague Kallen Konen, and Noelene Ahem of AuTec, Canada.
Kallen, Peter and Noelene
In the large audience I spotted two well known mineralogists, Hanna Horsch, of Hazen Research, USA, and Paul Gottlieb, of Tescan USA Inc.
And then I headed straight for the Press Room for the official launch of the  new SME journal Mining, Metallurgy & Exploration, which replaces and broadens the scope of the original Minerals & Metallurgical Processing (MMP). The new journal will be published by Springer Nature, and the first issue is dedicated to Prof. Douglas Fuerstenau on the occasion of his 90th birthday.

The afternoon Mineral Processing Division (MPD) session was devoted to prestigious awards. For the first time in my memory there was no Antoine Gaudin Award winner this year.
Dr. Jaime Sepúlveda was the recipient of the Robert H. Richards Award, which was established in 1948 to recognise achievement in any form that unmistakably furthers the art of mineral beneficiation in any of its branches.
In 1986, Jaime joined Moly-Cop, where after 28 years, he reached the position of Global Technical Leader. In 2014, he created J-Consultants Ltd., specialising in the design and optimization of mineral comminution and concentration processes. Jaime’s award citation reads: “For contributions to the advancement of comminution, support of research and education, and development of open-access, industrially accepted simulation tools (Moly-Cop Tools) for improving and optimizing grinding circuit efficiency.”  
Dr. Kathryn Sole was recipient of the Milton E. Wadsworth Award, which was established in 1992 to recognise distinguished contributions that advance our understanding of the science and technology of nonferrous chemical metallurgy. Kathy’s award citation reads: “Dr. Sole has made a significant impact on the development and practice of solvent extraction. Her academic contributions at the University of Arizona significantly improved the fundamental understanding of SX processes, and resulted in high impact publications.” 
After gaining much valuable experience at Mintek and Anglo American in South Africa, Kathy now consults independently, mainly in the areas of solvent extraction, ion exchange, and electrowinning of base and precious metals for hydrometallurgical applications. She currently chairs the SAIMM's Copper Cobalt Africa conference series and serves on the editorial boards of two journals.  
Kathy and Jaime
After Jaime and Kathy had presented their awards lectures, Dr. Seyed Hassan Amini was presented with the Rong Yu Wan Dissertation Award, by Nick Gow, a member of the MPD Scholarship Award Committee. Hassan is a postdoctoral associate at Virginia Tech, and the award was for his dissertation on "Optimisation of mineral processing circuit design under uncertaincy." 
Nick and Hassan
Prof. Douglas W. Fuerstenau then presented a fascinating keynote lecture, as a prelude to the Special International Symposium to Honour his 90th Birthday, describing his “Seven Decades as a Mineral Engineer: From the Black Hills to Butte, Boston, Berkeley and Beyond,” and Barb Arnold, SME President, then presented him with a special plaque from SME and the International Mineral Processing Council to commemorate this event. Prof. Fuerstenau is one of the great names in mineral processing, and I had the pleasure of interviewing him in 2015 for MEI. 
Prof. Cyril O’Connor, President of the IMPC, thanked the SME for giving him the opportunity to present personally award trophies and scrolls that the IMPC announced at the time of the 29th International Congress in Moscow last September, at which time unfortunately the recipients of these prestigious awards were unable to be in attendance due to problems associated with long-distance travel. These awards represent the very highest achievements that the IMPC recognises in terms of contributions to mineral processing. 
The 2018 Distinguished Service Award (DSA) was presented to Prof. Douglas Fuerstenau. It is also noteworthy that he becomes the first person in the history of the IMPC Congresses, which go back to London in 1952, to be awarded both the Lifetime Achievement Award as well as the DSA. After the presentation I was honoured to be invited to join Cyril and Doug for a photo of the present and former recipients of this Award. Humbling to think that Doug and I are the only living recipients of the award.

The second award,  the Lifetime Achievement Award (LAA), recognises a lifetime of distinguished achievement and outstanding contribution to the advancement of the art, science and industrial practice of mineral processing, together with participation in and contribution to IMPC Congresses. The 2018 LAA was presented to Prof. Jan Miller, of the University of Utah. His research achievements include outstanding contributions in the field of flotation and the surface chemistry associated with this process, particle/particle interactions and particle/bubble interactions, fine particle flotation, grinding/liberation analysis, the flotation chemistry of non-sulfide and fossil energy minerals, the application of X-ray microtomography to mineral liberation analysis, atomic force microscopy, the development of lithium-ion batteries, just to highlight a few aspects of his broad spectrum of research interests. Following the presentation there was another photo-call with former recipients of the LAA.

It was good to see so many well known mineral processors from around the world in the audience, including Profs. Kari Heiskanen (Finland), Zhenghe Xu (China) and Jim Finch (Canada). 
But it was particularly good to see Doug Fuerstenau with his wife Peggy and son Stephen
And if all that wasn't enough excitement for one day, I then rushed off to the Hyatt Regency Hotel for the official launch of the new SME Mineral Processing Handbook.
This is the result of the endeavours of six years of intense work by the authors, reviewers, editors, and SME book publishing team, photographed below.
Komar Kawatra, Jane Olivier, John Marsden, Diane Serafin, Rob Dunne, Karen Ehrmann, Terese Platten, Courtney Young
It is a truly mammoth effort, as the work is in two volumes of 2,312 pages, with 128 chapters. Each chapter is authored by an acknowledged expert, recruited by the editors, and each made an invaluable contribution. It was nice to know that two of my old Camborne School of Mines students contributed chapters. Dave Meadows, of Bechtel Mining & Metals, USA, I see at every SME, but Ted and Claire Bearman, of Bear Rock Solutions, Australia, I have not seen since Comminution '12, where Ted presented a keynote paper. He contributed three chapters on crushing to the new book.

Tuesday February 26th
A relaxing day planned today, with no agenda other than to stroll around the exhibits and see what transpires. As always I will avoid the technical sessions. The Fuerstenau Symposium starts this morning but is in parallel with other MPD sessions, on Physical Separation, Plant Design, Hydrometallurgy and Flotation Chemistry. So it would be unfair of me to comment on any individual papers, but invite comments if you feel that any particular paper is worthy of note.
Adam Johnston, Chief Metallurgist at cancha, Peru, regularly contributes to discussions on the blog, so it was good to talk to him about cancha's geometallurgy software, an integrated solution for geomet sample selection, result interpretation, prediction modelling and reporting (MEI Online). We are photographed below with Stuart Smith of Metifex, Australia.
Moving on I stopped to say hello to Nikhil Gupta and Serhat Keles, of Virginia Tech.
Nikhil and Serhat
I have known Paul Gottlieb for many years. He is one of the pioneers of automated mineralogy and is now with Tescan USA. TIMA-X is Tescan's integrated mineral analyser, an automated mineralogy system for fast quantitative analysis of samples such as rocks, ores, concentrates, tailings, leach residues or smelter products. It was good to talk to Paul (centre) and Regional Sales Manager Mike Craig.
I was pleased to see Swadhin Saurabh, recipient of the 2016 MEI Young Person's Award. Swadhin is Project Manager with Millcreek Engineering, USA, and is photographed with his colleagues Eric Morrison and Steven Kerr.
Eric, Swadhin and Steven
I have known Steve Hearn, of Huntsman, for many years. Huntsman is a supply partner to Quadra, a privately held distributor of speciality and commodity reagents. Steve is pictured 2nd right with Quadra representatives in their booth, talking to Deepak Malhotra, President of Prosolv Consulting, USA.
I last saw Bill Weldon two years ago in Falmouth at Physical Separation '17. Bill is a consultant with the IMSC Group, USA. IMSC (International Minerals Separation Components) Group is the exclusive service provider and manufacturer of Outotec Physical Separation product lines and parts. Founded in 2018, IMSC Group is dedicated to providing customer service, technical support, and proactive solutions that promote customer success.
Bill is pictured left on the photo below, with his colleagues Steve Stewart (2nd left) and Pat Cleaves (right). 3rd left is Peter Jansson, Technology Manager for Magnetic and Gravity Equipment at Outotec, USA. Outotec is a sponsor of Physical Separation '19, as well as Flotation '19.
Yesterday I had the pleasure of photographing Doug Fuerstenau, an IMPC Award recipient, with his wife Peggy, and son Stephen. Today it was an equally great pleasure to meet Pam Hoffmann, daughter of the other award recipient Jan Miller. Pam is Administrative Manager at University of Utah, and is pictured in the University booth with her father Jan, and Mike Nelson, Chair of the Mining Department.
After a great day I was back at the Hyatt Regency in the evening for the International Reception for all non-USA delegates. This was much better attended than in recent years, and was a very enjoyable couple of hours, despite having to queue for over 20 minutes for the one complimentary drink. 
 
Wednesday February 27th
Time for another short stroll around the exhibition, which closes at mid-day, before my flight back to London. It was vey quiet, as expected, but I did manage to catch up with a few people to say farewell, including the redoubtable Jane Oliver in the SME Bookstore.
Also good to see Nick Hazen, President of Hazen Research, USA, and some of his team. Hazen is an industrial research and development company, specialising in the mining, chemical, energy and environmental industries worldwide. The core business is performing and interpreting experimental work to provide design criteria and other technical information for new and existing processes. I'll bet that Nick doesn't remember that Hazen was the sole sponsor of Minerals Engineering '94 in Lake Tahoe a quarter of a century ago!

Last, but not least, I had a pleasant chat with Mining Engineering students from the "other CSM". Colorado School of Mines, situated in nearby Golden, was last year ranked world number 1 by the QS Rankings of Minerals & Mining Universities.
I have had an excellent few days in Denver, and the SME has once more lived up to its reputation as one of the great networking events. I look forward to being back in USA next year for the meeting in Phoenix. Congratulations, as always, to all involved with the organisation of this mammoth event.
 
Last year there was optimism of a resurgence in the mining industry, but unfortunately it did not happen. This year there has been a strong general feeling that we are at the beginning of a revival, and recent base metal prices do indicate some signs of recovery, but only time will tell.

There has been some concern, however, that if the industry does bounce back, supply might find it hard to cope with demand. Manpower in the industry is critical and there is a great need to attract young and talented scientists and engineers, as I highlighted in the posting of 17th December 2018. The perception that mining is a dirty industry run by capitalists must be dispelled, and the public educated that mining is crucial to society, and that mineral processing is mining's, and society's, most important technology.

  1. Thanks so much for the summary Barry. Its great to be reacquainted in a small way with people one has lost touch with. Shout out to Ted Bearman and Paul Gottlieb!

    Just on your last sentence. The days of the industry using rallying cries like "changing perceptions" and "educating the public" are long gone. The lived experiences of communities in and around Brumdhino and Bento Rodrigues in Minas Gerais make a joke of that idea. Its also wearing thin for society in general. The PR approach is failing and a new one that genuinely listens to host communities and the general citizenry about what matters to them, and where corresponding actions follow, is required. Relationship building has to be the new goal, not just "education".

    Thanks for the MEI forum you make available, Barry and yes, mineral processors rock!

    1. Thanks Rolf. I full agree with you regarding the need for relationship building, particularly in the wake of Minas Gerais. Suggestions as to how this might be achieved would be welcome.

    2. Cheers Barry, where to start on that invitation! PDAC is current running and the Sustainability Program has many sessions addressing social licence, so if people are interested, a glance at the new approaches, technologies and tools on offer there is a good place to start. At a very high level, the pathway to social licence goes through trust: a concept that the whole world would seems to be discussing at the moment, in many forms and contexts. In mining this means companies truly understanding what builds (and erodes) trust between with them and their host communities and responding accordingly. Thanks again Barry.

  2. As always, I am so impressed with the detailed coverage you give to important conferences like the SME. Your comments were interesting; photographs and write-up history -great. I feel like I was there!! You sure covered a lot of ground!

    Many thanks again for your report. I was thinking—if you didn’t do this—would there ever be a record? We are indebted to you.

  3. Dear Barry,

    thank you so much for this great review of the SME Denver conference also highlighting the Fuerstenau symposium, which was the initial reason for me to attend the conference. It was great to see you there and I totally agree it was one of the best networking opportunities I have ever had. Before attending mostly the Fuerstenau Symposium and the exhibition I had the pleasure to be guided through the Kroll Institute at the Colorado School of Mines in beautiful Golden by Prof. Patrick Taylor on sunday afternoon. At that time I already felt very comfortable in Denver and at the evening reception at the exhibition of the SME conference I knew this indeed would become one of the best events I have attended so far in my time as a mineral processor, letting me to put the future annual SMEs on my must attend list.
    On monday I enjoyed the very well selected keynote presentations especially by author Hannah Ubl and FLSmidth's Mikael Lindholm which really set a nice scene for the meeting. In the afternoon I attended the MPD with the award ceremonies. I still get goosebumps thinking about who was there. I told my group back home in germany it felt like being amongst the rockstars of our field, a true hall of fame. Those goosebumps remained until later that day when we had a dinner with the Fuerstenau symposium delegates (many rockstars again) which was organized by IMPC and the University of California Berkeley. I am so thankful for Cyril O'Connor and Jim Gebhardt for leading through the evening making t enjoyable and unforgettable. I will always remember the short conversation I had with Douglas Fuerstenau and also the opportunity to give a short greetings and gratulation address to both Douglas Fuerstenau and Jan Miller as the only representative from Germany. Both 2018 IMPC award recepients are not only great scientists and engineers but also wonderful people which I feel very honored to meet.
    On tuesday and wednesday I mostly enjoyed the wonderful talks at the Fuerstenau symposium and the intense networking in the hallways, at the exhibition and at evening receptions.

    Finally, I would like to pick up on your last sentence about the preception of the mining industry. I see a lot of great minds, wonderful good-will people striving for a better future. I have no doubt that what we do is most important and I also actively reach out to society which is always a lot of fun. But unfortunately I cannot shake off my own perception of still seeing a few but powerful and influential people with pure capitalist neoliberalist drive and it is so damn hard to talk to them. This is sometimes very depressing for me. But I hope they will never break the spirit of the long-term forward thinkers which do not solely take quick revenue into account.

    Best wishes from good old mining historical Freiberg, Germany (851 years of mining history),

    Martin

    1. Many thanks for this great overview, Martin. I'm glad you enjoyed the SME, I thought you might do! I'm also pleased that you picked up on my last sentence, as did Rolf Fandrich. I hope that this might lead to further useful debate. Looking forward to seeing you and your colleagues in Freiberg in October.

    2. 25% of cobalt produced is used in smart phones, and 60% comes from DRC. Cobalt demand is expected to double by 2025 with the development of the electric vehicle industry. Although major companies such as Gencore produce cobalt as a by-product from copper mining, this CBS News report, highlighting children mining for cobalt in the DRC in unregulated artisanal operations, shows that we have a long way to go in convincing the public that mining is a responsible activity.

  5. It's always a pleasure to welcome Barry to our SME Annual Conference & Expo!

    This year, our Mining, Metallurgy & Exploration (MME) journal, published with Springer Nature, launched with 23 articles in a very Special Issue on Mineral and Metallurgical Processing in Honor of Professor Emeritus Douglas W. Fuerstenau. In just over six months, MME has had 274 papers submitted, of which 54 are already published in print and online. Watch out for two more special issues lined up for this year: one on Emerging Technologies/Fourth Industrial Revolution in Mining in June and one on Critical Minerals in October.

    Thank you so much for your support, Barry, and I look forward to seeing you again next year in Phoenix!

  6. Hi Barry!
    Thanks for including IMSC Group in your blog. We really enjoyed seeing old friends at the show and meeting new ones. IMSC Group is dedicated to providing customer service, technical support, and proactive solutions that promote customer success while supporting the Outotec physical separation lines (formerly Carpco, Inprosys and Humphreys). It was inspiring to see how many people were enthusiastic about the continuation of production and support for these long established products.

  7. It was very nice to see you again in Denver and to interact with you on the occasion of the Monday awards afternoon of the Mineral Processing Division. You immortalized a few of the moments with the very good photographs you and others took that afternoon. Years ago, Gaudin Lectures (later Wadsworth Lectures) were at 1 PM before the start of afternoon technical sessions, then changed to 8 or 8:30 AM before the morning technical sessions started. This created people trying to get into the room before the award lectures were completed etc. Someone came up with the idea of having these activities on Monday afternoon, a time when there always was an all-institute roundtable panel which may not have had wide-ranging interest.

    You certainly presented a thorough tour of the exhibition showing many of the delegates visiting the exhibition hall. Of course many of those in your photos you know, but you must have a pretty good system of recording the names of those in your pictures.

    Thank you again for all of the kind remarks that you made during the recent events in Denver.

    My very best regards. DOUG
    Douglas Fuerstenau, California, USA
