Mineral Processing & Extractive Metallurgy board





From the chair:

Welcome to the board pages of the Mineral Processing and Extractive Metallurgy Division. Our purpose is to serve all members of IOM3 with interests in the processing of minerals to produce metals and other marketable products. We work closely with the other minerals-related divisions of the Institute to provide a focus both internally within the Institute and externally for the world-wide community of minerals engineers and extractive metallurgists.

The function of this website is to introduce the Division and its Board members and to explain our activities. I hope that you find this useful and would welcome any constructive comments.

Professor John Monhemius FIMMM - Past Chair of MP&EM

Professor John Monhemius

I started life in the RSM as a lowly assistant lecturer in the Metallurgy Department in the mid 1960s, in the heyday of the Nuffield Research Group in Extraction Metallurgy, which was led by Professor Denys Richardson, FRS.  After taking five years to complete my PhD, followed by a three-year leave of absence from Imperial to teach hydrometallurgy at the Federal University of Rio de Janeiro in Brazil, I slowly worked my way up the academic ranks, eventually becoming (the last) Dean of the RSM in 2001, the year of our 150th Anniversary.  I retired from the Deanship and full-time academia at the end of 2004.  After two or three years enjoying the novelty of retirement, I staved off impending mental ossification by joining the board of Anglo Asian Mining plc, a junior gold mining company with assets in Azerbaijan, as a part-time NED.  Since then, I’ve had great fun “doing it” instead of “teaching it” and have helped the company develop from a simple, small, open pit-heap leach, gold operation into a multi-mine company with heap leaching, agitation leaching and flotation facilities, producing copper concentrates, as well as 75koz of gold per year.





Professor Vasant Kumar FIMMM

Prof. KuDr Vasant Kumarmar, Head of Materials Chemistry in the Department of Materials Science at the University of Cambridge, has over 25 years of research experience in electrochemistry, energy and environmental devices, minerals chemistry and recycling of metals. He has published over 250 papers, 15 patents, 4 Chapters in Handbooks and 1 edited book (High energy density Li batteries, Wiley-VCH 2010; 2nd Edition, 2017). He has supervised over 35 PhD students, 25 post-doctoral researchers, 20 visiting students and hosted 10 visiting professors. Currently, Prof. Kumar’s research group consists of 12 PhD students, 6 post-doctoral researchers, 2 technical staff and 4 visiting scientists working on a number of research products underpinned by harnessing of interfacial chemical reactions in a variety of applications that range from mineral carbonation to sensors to batteries, fuel cells and photocatalytic reactions. Prof Kumar is the Editor of IOM3s journal Mineral Processing & Extractive Metallurgy since 2003.

Prof. Kumar has founded 4 spin-out companies for manufacturing sensors (EMC Ltd, S4H Ltd, CNS Ltd) and energy devices (CamSES Ltd). He works very closely with industry and research organizations and has successfully transferred many technologies to industry. For example, Prof. Kumar, has developed a new environmentally clean-process for recovering electro-active paste material from automotive- and off-grid renewables storage batteries for making new batteries (paste-to-paste recovery). Based upon a number of successful technical and financial evaluations, including by Johnson Control Solutions (USA), among the largest automotive battery company, Aurelius Environmental Ltd. have licensed the technology from the University of Cambridge and have set up a pilot-plant near Birmingham in 2016, with a view to globalize access to this technology. Prof. Kumar is a Technological consultant to AEL for in the development of the pilot plant at Tipton and data for manufacturing plants under advanced discussions in the UK, Belgium, USA, China, Brazil, India, S Korea and Taiwan.

From another research, Prof. Kumar has shown a method for using steel industry waste dust as a reagent for refining liquid iron, currently done using relatively expensive magnesium. Initial research work led to collaboration and successful plant trials with the steel industry in the UK and in China and currently, Prof. Kumar as a technical consultant, is participating on collaborative full scale plant trials taking place in Slovakia between University of Cambridge, Carmeuse (Belgium) and US Steel.
