Brief CV

Emeritus Professor John Monhemius held the Roy Wright Chair in Mineral and Environmental Engineering at the Royal School of Mines, Imperial College, London, UK, until December 2004, when he retired from full-time academic work. Professor Monhemius has more than 40 years experience of academic research in hydrometallurgy and environmental control in mining and metallurgical processes, particularly in the management of toxic wastes and effluents, and he has acted as a consultant to many large mining and chemical companies. He has published over 130 papers in scientific and technical journals and conferences and has supervised more than 30 PhD theses and many MSc theses. He was a co-founder and director of Consort Research Ltd., a consultancy specialising in gold and base metal ore processing. In 1994, he received the Gold Medal of the Institution of Mining and Metallurgy for research into the extraction of gold and in 1995, the MIRO John Phillips Medal for innovation and application of technology for the development of stable arsenical compounds for disposal of arsenic. Currently, he is a member of Council of the Institute of Materials, Minerals and Mining and is Board Chairman of the Division of Mineral Processing and Extractive Metallurgy. He is also chairman of the newly-formed International Mining and Minerals Association (IMMa). From 2000 to his retirement in 2004, he was Dean of the Royal School of Mines.
