Craig Klauber Editor

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.
