Farewells to a great bunch of process mineralogists

All too soon Process Mineralogy '17 came to an end this afternoon. Megan Becker summarised the past three days, and then Amanda Wills closed the event and invited everyone to attend Process Mineralogy '18, which will be held in Cancun, Mexico in November next year.
Practically everyone we talked to agreed that this has been a great networking event where new contacts and business have been made. It was particularly good to have a well known figure join us for the farewell wine function in the gardens, Prof. Cyril O'Connor, Chairman of the International Mineral Processing Council.

On behalf of MEI I would like to thank everyone who took part in this conference, particularly our sponsors, and we wish you all safe journeys home.
There will be a full report, with photos, on the conference next week.

The launch of the latest book on Process Mineralogy

Last week in Australia the Julius Kruttschnitt Mineral Research Centre (SMI-JKMRC) (part of the Sustainable Minerals Institute at the University of Queensland) celebrated the launch of the latest book in its series of Monographs on mineral processing. This most recent book, Process Mineralogy, is edited by a team of three people whose names will be familiar to those working in this field - MEI's process mineralogy consultant Dr Megan Becker, of the Centre for Minerals Research at the University of Cape Town, and Drs Elaine Wightman and Cathy Evans of the SMI-JKMRC
The launch party at SMI-JKMRC celebrated the hard work of the three editors of Process Mineralogy and their 50 contributors from around the world, which has culminated in the production of this comprehensive review of the current state of the art in applied mineralogy. The support of Dr Ying Gu, Prof Dee Bradshaw and Prof Ben Adair in the initial stages of the book helped the editors to build a team of contributors which spans our industry in terms of both commodity type and geographical location. While the list of contributors is too long to be included here, readers of the Process Mineralogy book will recognise many of them as regular attendees at the biannual MEI Process Mineralogy Conferences. The breadth and depth of the knowledge shared by the contributors in each of the book chapters reflects their expertise in mineralogy tools, techniques and their application and make this book unique.
Prof Neville Plint, Director of the SMI and Prof Alice Clark, Director of Production Centres at SMI welcomed a number of the Brisbane-based contributors, including Dr Bill Johnson, Dr Greg Wilkie, Dr Graham O'Brien, John Knights and Prof Malcolm Powell who came along to join JKMRC staff, students and alumni in the celebrations.

Prof. Neville Plint (Director, Sustainable Minerals Institute)
Process Mineralogy '17 provided an opportunity for a 2nd launch, and for Cathy and Elaine to catch up with Megan and the contributors based in South Africa.

Evening dinner by the lagoon

A beautiful location tonight for the Process Mineralogy '17 conference dinner, overlooking Lagoon Beach in Milnerton, with its stunning view of Table Mountain and Lion's Head.
After the 35C heat of the day, it was great to relax in the warm late afternoon sunshine, with drinks on the terrace before an excellent buffet meal in the impressive Lagoon Beach Hotel restaurant.
There will be many fond memories of the evening, and cameras were clicking furiously to provide permanent reminders of the evening and the very interesting and amiable people who make up the world of process mineralogy. Some of the images are shown here- there will be more next week on the conference report.

MEI's Conference bags proving popular

It's not often that you hear positive comments on conference bags, but many of this week's delegates have provided positive feedback on MEI's colourful bags. We are particularly pleased about this as the bags are hand-made in Cape Town's sprawling Khayelitsha township by Learn to Earn, as part of their Feel Good Project, which is dedicated to creating opportunities for employment and alleviating poverty in South Africa. Together with TFG (The Foschini Group), Learn to Earn provides unemployed individuals with the skills required for the retail sector so that they may enter and sustain careers in this fast-paced industry.
It is also nice to have positive feedback on the conference lanyards, made by Kidzpositive, a non profit organisation dedicated to improving the lives of children and families affected by HIV/AIDS and other chronic diseases.

Dr. Norm Lotter to be honoured in Mexico

Amongst the eminent mineral processors at this week's Process Mineralogy '17 is Dr. Norm Lotter, President and Consulting Engineer, Flowsheets Metallurgical Consulting Inc, Canada, who was a keynote speaker at Process Mineralogy '10. Norm has been nominated for the Fray International Award recognising his contributions to the profession of mineral processing across his career. The award will be presented at the SIPS summit conference in Cancun, Mexico, in October, at which there will be a symposium honouring his contributions.
Norm is pictured left with Prof. Dee Bradshaw of the University of Cape Town, who is on the organising committee for the Lotter Symposium.

Happy hour under the trees

A baking hot day today, just what Cape Town does not need. As two of our presenters, travelling from Tasmania, have been very seriously delayed, their papers have been postponed until Wednesday, so this afternoon's Happy Hour was slightly earlier than scheduled.
I talked this morning in my opening remarks of the importance of networking, and the shade of the trees in the Vineyard gardens provided the perfect setting to relax and chat over a few glasses of pinotage and sauvignon blanc.

Process Mineralogy '17 off to a great start

I opened the conference this morning, welcoming the 97 delegates from 21 counties, and thanking our sponsors for their support.

Eric Pirard of the University of Liege, Belgium then presented his keynote lecture on process mineralogy's role in boosting the circular economy.

It is great to see my old friend Alan Butcher back at an MEI Conference. Alan played a big part in the development of the concept for the Process Mineralogy conferences. While at Intellection in Australia, Alan forged a link between the company and MEI to run annual conferences on Automated Mineralogy in Brisbane. Commencing in 2006, these proved successful until the collapse of Intellection in 2008, after which we moved the conferences to Cape Town in 2010, as the biennial Process Mineralogy series, of which Process Mineralogy '17 is the 4th in the series.
Alan and I at the first Automated Mineralogy conference in 2006
Alan and I were colleagues at Camborne School of Mines before he joined CSIRO in Australia, and then Intellection. He joined FEI when Intellection's assets were taken over by FEI, and he has recently been appointed to a senior research position at the Geological Survey of Finland (GTK), as professor of geomaterials and applied mineralogy. It is a brand new role at GTK and reflects the recent changes in strategy by the organisation, which is developing new areas of innovative research that can lead to growth in areas not traditionally carried out by geological surveys in any detail, such as the detailed study of commercially important geomaterials (for example the applied mineralogy of ores, building stones, aggregates, soils, and various mineral based-man-made materials).
Particular topics expected to be targeted in the future include innovative approaches to geometallurgy, process mineralogy of ores, man-made product manufacture, and advanced mineral analysis methodologies. One area of general operating philosophy in Alan’s work is the concept of cross-disciplinary research, whereby engineers and scientists closely work together in collaborative teams, and use their combined experiences and skills to solve common challenges. This is a practice he has learnt, to great effect, from his time spent working with, for example, geophysicists, reservoir engineers and reservoir quality geologists, on petroleum industry projects whilst at FEI.
An emotional Alan receives his honorary MEI cap!

Weekend in Cape Town

Barbara and I arrived in Cape Town at mid-day Friday, and the view from the plane approaching the city was sobering, an unusually dry, arid landscape, as the prolonged drought has left the city's reservoirs less than 30% full, and with only 100 days supply of water remaining.

Saturday was a day of rest to recuperate from our 24 hour journey from Falmouth. Amanda and Jon arrived mid-day, and in the evening Barbara, Amanda and I, together with Elsevier's Dean Eastbury, were the guests of Roger and Janet Thomas (see posting of 19th April) at their home in Constantia. A great evening of good company and an excellent ostrich potjie, accompanied by fine wines from Rustenberg and nearby Kleine Constantia. 
Janet, BW, Barbara, Dean, Amanda and Roger
Sunday was cloudless and very hot, not great for the water shortage. Conference sponsor Zeiss ran a whole day workshop on x-ray microscopy, attended by 42 delegates, a record for a workshop associated with an MEI Conference.

And then Process Mineralogy '17 got underway late afternoon with registration and welcoming cocktails in the exhibition area.

Memories of Complex Ores '97 Bulawayo

Process Mineralogy '17 gets underway tomorrow in Cape Town, and 20 years ago tomorrow, across the Limpopo, our first and only conference in Zimbabwe commenced.
Terry Veasey

Complex Ores '97 was organised by CSM Associates Ltd, and Camborne School of Mines, and was held at the Bulawayo Sun Hotel. The keynote lecture was given by Birmingham University's Terry Veasey, who at that time was a visiting Professor at the National University of Science & Technology in Bulawayo. Below are some photographic memories of that brief but enjoyable time in Zimbabwe.

Join us in Cape Town next week

Barbara and I leave for the long journey from Cornwall to Cape Town this morning, and Jon and Amanda follow tomorrow.

Process Mineralogy '17 commences Sunday afternoon, and registration is still open, so it is not too late to join us and the other 95 international delegates who will be there.

Apart from the fine technical programme, this will be a great opportunity for networking, and I will be posting news and photos of people all next week on the blog and on Twitter (@barrywills).

A Rising Star: Przemyslaw B. Kowalczuk

The 3rd person in our Rising Star series is a 34 years old Polish associate professor at the Wroclaw University of Science and Technology, Faculty of Geoengineering, Mining and Geology, Wroclaw, Poland, who has impressed us when we have met him at several international conferences.
The professional career of Przemyslaw (Przem) Kowalczuk in mineral processing began when he met two outstanding Professors, Tomasz Chmielewski and Jan Drzymala from the Wroclaw University of Science and Technology.
Przem (2nd right) with Tomasz Chmielewski, Janusz Laskowski
and Jan Drzymala at IMPC 2014 in Santiago
Tomasz encouraged him to study hydrometallurgy, and then Jan mineral processing. During his master study Tomasz, who was his supervisor, was also leader of the BIOSHALE 6th Framework Programme project entitled Search for a sustainable way of exploiting, black shale ores using biotechnologies, and Przem participated in this, working on non-oxidative and atmospheric leaching of the shale fraction of the Kupferschiefer copper ore. In 2008, the project and his study ended and he started to look for a job.
“Luckily, I found that the group of Mineral Processing was hiring a laboratory technician” he says. He applied and during the interview Prof. Drzymala suggested he become his doctoral student. “I could not say no since it was a great honour to work for such a great scientist” said Przem. During his PhD study he worked on his thesis entitled Theoretical and experimental determination of the maximum size of floating particles in different devices as well as a number of other scientific activities.
In 2009 Oktay Sahbaz (now Professor at Dumlupinar University, Turkey) visited Wroclaw as an Erasmus student. “During his four-month stay in Poland we worked together on flotation and became friends (he still calls me ‘kanka’, which in Turkish means the best friend)”.

and his family during a visit to Dumlupinar University in 2013

and supervisor Prof. Jan Drzymala
In May 2012 Przem defended, with honours, his PhD thesis and then spent, first as an Erasmus student, and then as a research assistant, “an absolutely wonderful six months” in the scientific group of Prof. Hylke J. Glass at the Camborne School of Mines, University of Exeter, where together with Shekwonyadu Iyakwari (now Professor at Nasarawa State University in Keffi, Nigeria), he dealt with research and analysis of Near Infrared Spectroscopy and Qemscan® of copper ores. When he returned to Wroclaw, his research focused on improving the theory of flotation of naturally hydrophobic surfaces. He says that “it would not be possible without the co-operation of my great professors and friends: Jan Drzymala from Wroclaw as well as Kazimierz Malysa and Jan Zawala from the Polish Academy of Science in Krakow. Up to the present, I have closely cooperated with all the mentioned great professors and scientists, whereby the quality of my professional life is still improving”.

and Mrs. Agata Barczak
I asked Przem what interesting things he has been doing lately. He said “during my research career I have been working on a number of scientific activities including mineral processing, hydrometallurgy and geometallurgy. Recently, I obtained my DSc (habilitation) in mining and geological engineering (specialization: minerals engineering, materials engineering, physicochemistry of surfaces). My academic accomplishment were presented based on a series of published papers (JCR) combined into an essay on Physicochemical aspects of flotation of naturally hydrophobic substances”.
He continued “my research work was also related to other aspects of mineral processing and hydrometallurgy. I was involved in several industrial projects conducted for KGHM Polska Miedz S.A. The projects dealt with, for instance, i) preflotation of copper ore using only frothers, ii) a possible use of the Jameson cell in copper ore flotation at KGHM (in collaboration with Prof. Oktay Sahbaz from Dumlupinar University in Turkey), iii) analyses of copper ore beneficiation results on the industrial scales. Together with Prof. Adem Tasdemir (Eskisehir Osmangazi University in Turkey) we developed a methodology for monitoring the copper ore beneficiation process at industrial scale (KGHM Polska Miedz S.A.)”.
He also took part in a hydrometallurgical project led by Prof. Tomasz Chmielewski. “We worked on the method for the hydrometallurgical processing of polymetallic raw materials mined by KGHM. The developed new technology has been patented and is ready to be implemented”.

In collaboration with Hylke Glass’s research group from the Camborne School of Mines, he worked on recovery of cobalt from the Kupferschiefer copper ore, together with Tomasz Chmielewski, and a PhD student at the University of Exeter. The PhD is a part of a CoG3 - Cobalt: Geology, Geomicrobiology, Geometallurgy project led by Prof. Richard Herrington from the Natural History Museum in London. The main aim of the CoG3 project is to understand the natural behaviour and biogeochemistry of cobalt in order to develop and apply novel bioprocessing strategies for cobalt extraction, recovery and the synthesis of targeted products using an integrated multi-institute and multidisciplinary approach.
In 2016 “I had the great pleasure of organizing, as a vice-chairman, the International Mineral Engineering Conference MEC2016 with MEI as a media partner. It was a great opportunity to meet and host in Poland an excellent mineral engineering community from different countries. The MEC2016 conference proceedings were published in the E3S Web of Conferences journal in volume 8: Mineral Engineering Conference MEC2016 edited by myself and Prof. Jan Drzymala.” Przem is also the co-editor-in-chief of Physicochemical Problems of Mineral Processing journal.

Przem tells me that beginning in March he will spend 2 years involved with the MarMine project led by Prof. Rolf Arne Kleiv at the Norwegian University of Science and Technology. He will be working as a post-doctoral fellow in mineral processing with a focus on processing of seafloor massive sulphide deposits.
He says that “in the long term I would like to have my own research group working on fundamental aspects of mineral processing, especially investigation and numerical dynamic modelling of the phenomena occurring in the solid/liquid/gas interfacial systems, as well as application of the findings in industrial settings to develop new more effective technologies of beneficiation of ores. I like mineral processing since there is still plenty to do. The sky is the limit!”
With so much going on I wondered what were his outside interests and he said “outside my busy professional life I do not have a great deal of time for other interests. However I like cycling, travelling and reading. Every year, together with my friends, I try to visit different places in Europe and other continents. My holidays, in the last three years, were spent traveling through most amazing and unforgettable places in Europe and North America. This year I plan to be closer to nature exploring Scandinavia and Alaska”.
Przem is obviously a young man dedicated to mineral processing. It has been a pleasure talking to him and I am sure we will hear much more of him in the future.

People news from both sides of the pond

We are delighted to announce the birth, on Monday, of Seth Wills, a healthy 8 lb 12 oz (3.97 kg) boy, to MEI's Jon and his partner Dr. Kathryn Hadler. Seth's sister, Josephine, who was 4-years old on Thursday, is naturally delighted! Many congratulations from me, Barbara, and Amanda and family.
Fifteen miles from Jon's family home in St. Agnes is the small village of Mabe, just 2 miles outside Falmouth, and home to MEI's Amanda and family. Each year Amanda displays her thespian talents in the Mabe Village pantomine (oh yes she does!) and last night Barbara and I were in the audience for The Pied Piper of Primelin (Primelin is the French village twinned with Mabe), where Amanda took on two parts, and her boys were two of many 'knicker stealing rats'.
Although not exactly of Stratford standard, what made it so enjoyable was the sheer enjoyment on the faces of all the players.

And finally news of people from across the Atlantic. The SME Scotch Night Cap is an annual fundraising event providing scholarship money to new students. At this year's Scotch Night Cap, which took place during the SME Meeting in Denver, the traditional Scotch tasting was supplemented by live music and the first performance of the group Bass Metals, formed entirely of mineral processors.

The band was formed following a late night jam session at last year's IMPC in Quebec City, where Dave Meadows, formerly with FLSmidth, now with Bechtel Mining and Metals, USA, played with Quebec Blues Guitarist Mike De Way in one of the old town Irish bars. Dave met up with Joe Mercuri from the global technology and product development company CiDRA and they initiated the band aptly named Bass Metals. Joining Bass Metals in Denver were John Marsden of Metallurgium, Nick Hazen of Hazen Research Inc and Nayitha Advincula formerly of FLSmidth, Joe Mercuri fronting the stage with his powerful full on rock singing. It was apparently a great event with excellent ticket sales and we look forward to seeing Bass Metals at next year's SME conference in Minneapolis.

Flotation Chemistry vs Flotation Physics

I have had an interesting email from a very eminent flotation researcher, which I am sure will generate some debate. He/she would prefer to remain anonymous as he/she feels that industry has a reputation for judging the whole department by any individual. I publish the email below with only minor edits:
Question – currently, why is so much attention (≡ to money) being spent on the comparatively narrow study of the physical aspects of flotation, at the expense of flotation chemistry studies? A good example is the current preoccupation with coarse particle recovery.   
As a starting point we should ask ourselves - ‘What is flotation all about, really’? The answer is straightforward - the ‘Holy Grail’ of flotation is selectivity not recovery. After all if we take an ore body and do nothing we have 100% recovery, but the product, as such, is useless. Recovery without selectivity is all in vain. However there seems to be a meagre acceptance of the importance of grade.

Little is said about selectivity but there is a constant cry for increased recovery. This might be what industry wants but it is certainly not what industry needs. However, physics based studies are merely concerned with increased recovery not increased selectivity; selectivity in flotation is only achieved by attention to the pulp chemistry. Yet, currently, there appears to be little (research) money being directed towards chemistry based flotation studies. Strong, and successful, chemistry based research groups like those at CSIRO and The Wark have all but disappeared because of a lack of (financial) support. 
As natural resources become more and more scarce, and more and more complex, their value will be determined more and more by the degree of selective separation which can be obtained in processing. This can already be seen for arsenic contamination. And selectivity against pyrite will increase in significance, exponentially. So, we might well ask if the current strong financial support for the physical aspects of flotation is misguided. 
For example. An actual case study - the treatment of a sulphide ore. For the rougher stage, recovery beyond 85% was difficult. The rougher concentrate, at 85% recovery, could be worked up to a smelter acceptable product of 25% grade; the tailing assay was 0.09%, with most of the loss in the coarse (-500+40 micron) size fraction. With some effort (in a laboratory) it was possible to do a size split (at 40 micron), retreat the coarse fraction, and recover another 10% of the values in a scavenger product (ie lift overall recovery to 95%). Assay of this scavenger product was about 1%. This gives a ratio of concentration of about 10, similar to what was (and is commonly) achieved in the rougher stage. However, no amount of retreatment could raise the assay of this product above 6%, and this grade is not acceptable at the smelter. Accordingly, in practice, these particles, after initial recovery, would have ended up back in the tail. Therefore, in this case, any money spent on installation and operation of special cells for recovery of these coarse particles would be misguided.  
Second (obvious) question. How many of the researchers seeking special ways of increasing the recovery of coarse particles (for example) have thought of what they are going to do with these particles when they are recovered; perhaps the final recovered value is less than the cost of recovery? 

Third more important question. How many of the people putting up the money for this research even understand the problem? And would some of the currently available research money be better spent on further understanding the problems of, and developing techniques for, upgrading low grade concentrates?
Flotation chemistry studies are certainly more difficult than physical flotation studies; what is not generally recognized is that they are also more important.
And all this prompts the last question – does anybody really care?

Strong opinions and I invite further strong opinions! Personally I found "...but there is a constant cry for increased recovery. This might be what industry wants but it is certainly not what industry needs" contentious. Increased recovery may or may not be what industry needs. But what about society? As we move towards a circular economy isn't maximum recovery of natural resources, at optimal grades, what we should be aiming for? And is there more to increased recovery at optimum grade than just flotation? Comminution-liberation must play a big part in this (but that's another story). Hopefully we will hear much more about this at Flotation '17 and Comminution '18.

Well known mineral processors inducted into the International Mining Technology Hall of Fame

Inductees from the 2015 and 2016 International Mining Technology Hall of Fame were presented with their awards during a Gala Dinner on February 20th 2017 at the Brown Palace Hotel & Spa in Denver, Colorado, the same week as the SME Annual Meeting.
Among the many awards were those in the Comminution, and Concentration categories. The 2015 Comminution award was made posthumously to Fred Bond, synonymous with grinding circuit design, through the Bond Grindability and Bond Work Indexes that still bear his name. The award was presented to Fred Bond's son, Bruce. The Concentration award was made to Sandy Gray, of Gekko Systems, Australia, one of the keynote speakers at Physical Separation '17 in June, at which International Mining is a media partner.
Bruce Bond, Sandy Gray and International Mining's Paul Moore
The Comminution award for 2016 was made jointly to two inductees, Joe Pease and Dr. Bill Johnson, and the Concentration award to Dr. Nag Nagaraj (see posting of 2 February for more details).
Joe Pease, Bill Johnson and Nag Nagaraj
International Mining is seeking nominations for the next two years of inductions (2017/2018) which will be celebrated in February 2019, again in Denver during the SME week. Categories relevant to mineral processing include Comminution, Concentration, Metallurgy and Environmental Management & Stewardship. There is also an Outstanding Innovator category. Nominations can be sent to John Chadwick at or Paul Moore at any time from now until end-August 2018, when the voting process will begin. They need 500+ words on the person or people (a development team for example) being nominated, what the innovation is and what it has achieved that has helped take the industry forward.
