IntegratedMinPro '22: the deadline for abstract submission is only a week away

Just to remind you that if you would like to present a paper at Integration, Optimisation & Design of Mineral Processing Circuits (IntegratedMinPro '22), MEI's online conference in June, then the deadline for abstract submission is the end of next week.

This exciting new conference covers new approaches to mineral processing circuits, whether through design, modelling, optimisation or operation. This includes integration of unit operations (e.g. comminution and flotation), novel flowsheets that incorporate new equipment and new approaches to optimising circuit design.

A must for anyone involved in mineral processing operations.

We welcome Steinert as the 3rd sponsor of Physical Separation '22

One hundred and fifty years ago miners had two methods available to upgrade ores, gravity concentration and hand sorting. With the advent of flotation and the need to treat more finely disseminated ore bodies hand-sorting rapidly declined in importance, although gravity concentration is still the method of choice when mineralogical properties allow.

Gravity concentration will be a major topic at Physical Separation '22 in May, but so will sorting, as modern electronic sorters are playing an increasingly important role in reducing energy and water requirements on modern mines. 

Sensor technology enables fully automated sorting of materials whose differences would otherwise only be representable using complex analyses. New methods of induction or x-ray technology offer ideal conditions for clean metal concentrates or valuable metal-free residues and for standards of efficiency, and one of the leading companies in this field is Steinert, who we welcome as a sponsor to Physical Separation '22.

Steinert joins Hudbay Minerals and Gravity Mining as sponsors, our Media Partners International Mining and Imformed, and our Industry Advocates the Coalition for Eco-Efficient Comminution (CEEC), the Cornwall Mining Alliance and the Critical Minerals Association.

Although the formal deadline for abstracts has passed, we still invite submissions if you would like to present at the conference, which will be held online from May 9-11.

MEI Young Person’s Award 2021 to Paulina Quintanilla

We are very pleased to announce that the recipient of the 2021 MEI Young Person's Award is Paulina Quintanilla, at 29 years of age an outstanding early career researcher at Imperial College, UK.
Paulina holds a Chemical Engineering degree from Universidad Tecnica Federico Santa Maria (UTFSM) in Chile, where she received several awards for her excellent academic performance, including being the top student in her cohort and the 2017 Award to the Best Chemical Engineering graduate from the Chilean Engineering College. 
After her master’s degree, she was also a researcher and part-time lecturer at UTFSM in 2017-2018. Paulina started her PhD under the supervision of Dr. Pablo Brito-Parada in October 2018, in the Department of Earth Science and Engineering at Imperial College London. Her background and research experience on supervisory control have been instrumental in her work towards the development of a holistic model predictive control strategy for froth flotation. 
Her PhD is fully funded by the Chilean government, with a scholarship awarded to the very best students in Chile. During her PhD, she has published a thorough critical review and 2 papers in Minerals Engineering. Her PhD work represents a step change in advanced modelling for flotation control, and Dr. Brito-Parada expects that  she will finish her PhD (by the end of this year) with at least 2, if not 3 additional publications arising from her thesis.
Paulina has presented at a number of local and international conferences, receiving excellent feedback. She has achieved this despite COVID-related delays on experimental work, and in fact made an opportunity of this challenge, establishing a collaboration in Chile to run tests remotely from the UK to implement the control system she developed. She secured funds to carry out further work in Chile and to visit a Chilean mine to gather data to validate her PhD work on site.
At Imperial, Paulina has been a proactive member of the Department of Earth Science and Engineering, contributing as a Graduate Teaching Assistant (GTA) for 4 undergraduate modules and more recently as a GTA coordinator. She has also been involved in multiple outreach and science communication events and has attended summer schools on extremely relevant topics to our discipline: on circular economy and metals processing (Aalto University, 2020) and on optimisation and machine learning (via selection process, ITB, Indonesia, 2021).
The Science and Chemical Industry recognised her research potential by awarding her a prestigious Messel scholarship in 2020 to support both her work and outreach activities and she has actively, and successfully, applied for additional funding for her work. As further indication of her excellence in research, she led a collaboration (independent of her PhD supervisors) to develop an open-source software for bubble size analysis, which has now resulted in a paper submitted for publication. This all while being active in disseminating her PhD outcomes, with 4 conference presentations last year alone, receiving fantastic feedback for her talk at MEI’s Flotation '21.
On a more recent note, and a tremendously exciting one, Paulina was selected among hundreds of applicants to present her work at the 2022 Stem for Britain event, a major scientific poster competition and exhibition by early career researchers that took place on 7th March in the Houses of Parliament. Paulina was one of the 33 finalist selected to represent the field of Engineering, following an extremely competitive process. Her poster was entitled “Towards the optimisation of froth flotation: the transition to green energy will need bubbles!”. Notably, Paulina's work was the only one to focus on mineral resources/processing, which is of course very timely, and even more so as she presented it not only to a panel of experts but to a range of politicians. 

Dr. Brito-Parada says that Paulina is fantastic at science communication and such a great ambassador for our mineral processing community. She is undoubtedly a worthy winner of the MEI Award, which we hope to present to her at Process Mineralogy '22 in Spain in November.

Memories of the CSM class of 1977

Passing by the town's oldest hotel, the Falmouth Hotel, I was pleased to see three of the Camborne School of Mines 1977 alumni, down here for tonight's annual dinner.

Mark Pearson is over here from Denver, USA, where he is President and CEO of Liberty Resources, an oil and gas company whose principals are recognised as global experts in hydraulic fracturing and other technologies. After graduating in mining engineering at CSM Mark went on to be awarded a PhD for research into explosive and hydraulic fracturing of granite rocks for geothermal energy extraction.

Kwabena Kwakwa ("Kwa") also went into the oil and gas field after graduating and has long experience as a geomechanics specialist with worldwide experience in adding value to upstream oil and gas projects, and has been with Energy Technology Associates Ltd, UK for over 21 years.

For over 42 years Chandra Durve has been a consultant mining and tailings disposal and dam stability specialist.

Reunion with Kwa, Mark and Chandra

I have particular memories of Kwa and Chandra as they were regular members of the CSM Cricket team in the 1980 debut season.  I look forward to talking to them more this evening at the dinner.

A few surprises at the Cornish Mining Sundowner

There were a few regulars missing last night, due to Covid, which is enjoying a bit of a comeback down here in Cornwall. However there was a great turnout at Falmouth's Chain Locker for the March Mining Sundowner, as there were a few surprise guests, down here for tomorrow's Camborne School of Mines Annual Dinner in Falmouth. 

I was particularly pleased to see Helen-Louise Colbourne (née Leach), CSMs 3rd female mineral processing graduate, who graduated in 1989 and then did a post-graduate Diploma in Mineral Processing, before leaving for South Africa and Impala Platinum. She had some fascinating anecdotes about her time as the only female mineral processor on the mine. In 1997 she and her husband, CSM Mining Engineering graduate Chris Colbourne, moved to Australia, where she had many top jobs, including a long spell with Rio Tinto in Perth and in the UK (see also posting of 10 December 2016).

Not suspecting what would happen just over a year later, Helen-Louise (H-L) and Chris moved to Moscow in December 2020 and they were loving life there there until the awful war with Ukraine began, and life fell apart a few weeks ago.

H-L told me that on a beautiful balmy afternoon in Perth in December 2020, she said goodbye to her beautiful twenty-year-old daughter Sophia and said that the emotional pain of a mother, not knowing when they would see each other let alone be allowed back into the country was intense. The international airport was showing obvious signs of pandemic controls everywhere, something the rest of Western Australians had fortunately not seen in the community, which to that point had largely escaped the terrible high numbers of Covid infection seen elsewhere in the world. 

Chris had been offered work in a gold mining company with operations in Russia, Kazakhstan, Burkina Faso, and Guinea with growth projects in various locations around the world and H-L planned to start a PhD focusing on the impact of Front-Line Leader capabilities on their team’s safety performance.

They moved into a fully furnished apartment with only a few modern luxuries to add to make life easy and H-L was determined to learn Russian and soon embarked on learning through Zoom lessons the new way of meeting and communicating. The impact of the pandemic was keenly felt in Russia although a strict lock-down was imposed in early 2020, as experienced by most in the world, and as soon as Sputnik V was available to expats, they stood in line to take the vaccine determined to help with the fight against this terrible disease.

One of her favourite activities was the walking group in Gorky Park organised by the Irish club and each Saturday they would meet at the front of Gorky Park and stroll quickly along next to the Moskva river, sometime in temperatures she had never experienced. She said that the bunch of pals they met there will be life long, all spread across the world now as these terrible events unfold. H-L fervently hopes for the very best and a swift resolution and that the people of Russia can once again be celebrated and travellers can return.

She was fortunate to be at last night's sundowner, as the escape from Moscow was traumatic. H-L needed to get back to UK to see her ailing 87 year old father but direct flights were not possible as the UK blocked Russian planes soon after the Ukraine invasion, so she tried in vain to leave via Germany and then Istanbul. On Sunday Feb 27 she boarded an Aeroflot flight to Paris, but within an hour of landing the captain announced that they were heading back to Russia as France had closed the airspace whilst they were flying. Fortunately Chris's company helped them both to find a flight via Dubai then on to London. They arrived two weeks ago and she was very relieved last night to be among old friends at the Chain Locker.

It was a special evening yesterday and I look forward to catching up with many more past students from around the world tomorrow night.

The next sundowner will be at the Chain Locker on Thursday 14th April from 5.30pm.
