Clays in the Minerals Processing Value Chain

About this book

Clays are increasingly becoming a major problem in the mining, extraction and value-adding processes for a wide range of commodity raw materials. Clays can impact negatively on virtually every unit process within the mining and minerals processing sector, having long-term environmental implications that go well beyond the lifetime of the mining operation. Clays in the Minerals Processing Value Chain is the first to compile, explain and evaluate the effects of clays in the mineral processing value chain, from mining to minerals processing, and finally, tailings disposal. Focusing on topics from the chemistry and rheology of clays to their detection and dissolution behaviour, Clays in the Minerals Processing Value Chain provides comprehensive coverage of the effects on processes such as settling, preg-robing, flotation and comminution. It is an excellent reference for professional mineralogists and geologists, industrial engineers, and researchers interested in clays and clay minerals.

Biography

Markus Gräfe is the National Coordinator of the Department of Soil and Water Management at Ecuador's National Agricultural Research Institute (IN-IAP), and an Associate Editor for the Journal of Environmental Quality. His research focuses on Ecuador's soil mineralogy and chemistry, stretching from the Amazon Basin across the Andes to the Pacific Ocean and Galapagos.

Craig Klauber came to mineral processing research from a background in fundamental surface chemistry and spent several decades as a research scientist at the Commonwealth Scientific and Industrial Research Organisation (CSIRO). His work principally focuses on utilizing X-ray photoelectron and Auger spectroscopies in order to solve problems in mineral processing systems. He is currently an Adjunct Professor at Curtin University of Technology, Perth.

Angus J. McFarlane is a senior geoscientist for the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Mineral Resources, with expertise in applied minerology and geometallurgy. He is currently working on projects which enable scientists and mining professionals to link ore properties and their behaviour during mining processes via improved characterization and data analytics techniques.

David J. Robinson is the Group Leader for Base and Precious Metals Processing within CSIRO, where he has been since 2007 following a twenty-year career at Anglo Platinum and Anglo American. He leads a number of research- and pilot-scale projects in base metals hydrometallurgy in areas such as mineral characterization, geometallurgy, leaching, refining and solvent extraction.
