Emeritus Professor John Monhemius held the Roy Wright Chair in Mineral and Environmental Engineering at the Royal School of Mines, Imperial College, until 2004, when he retired from full-time academic work.  From 2000 to 2004, he was Dean of the Royal School of Mines.  He has more than 50 years' experience of academic and industrial research and development 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. Professor Monhemius has published over 150 papers in the scientific literature and he has supervised more than 30 PhD students.  From 1986-96, he was a co-founder (with Professor A.R. Burkin) and director of Consort Research Ltd, a consultancy based in the Royal School of Mines, specialising in gold and base metal ore processing. 

In retirement, he joined the board of Anglo Asian Mining plc, a junior gold mining company with assets in Azerbaijan, as a part-time NED, where he has 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 70koz of gold per year.
