Frank K. Crundwell

Frank K. Crundwell is Director of Crundwell Metallurgy Limited, London, UK, CM Solutions (Pty) Ltd and is a Visiting Professor at the University of the Witwatersrand, South Africa. He has worked in research institutes, industrial refineries academia and consultancies. He founded CM Solutions back in 2002, a sustainable laboratory and consultancy to the metallurgical industry. It develops flowsheets for a large variety of metals, such as copper, cobalt, gold platinum-group metals, nickel, and zinc, with a current focus on high purity products. Frank has more than 40 years’ experience in studying dissolution reactions, and more than 70 publications in the area. He has been awarded the Milton E. Wadsworth Award of the Society for Mining, Metallurgy and Exploration for “innovative, rigorous contributions that have enhanced fundamental understanding of the mechanisms of oxidative and non-oxidative leaching of minerals including sulfides, oxides and silicates”. He was elected to the prestigious National Academy of Engineering (US) for this work.

He has contributed to and solved several debates in the field: (i) how bacteria interact with minerals, (ii) mechanisms of quartz and silica dissolution (iii) how impurities impact dissolution. In addition, he has contributed to the electrochemical theory of dissolution, extending it to apply to dissolution of semiconductors. He previously co-authored the Elsevier book Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals (2011) with Michael Moats, Venkoba Ramachandran, Timothy Robinson, and W. G. Davenport.
