For the laymen (Why should someone buy this book? Catching general description of the topic for a non-scientist)) The field of hydrometallurgy includes the techniques by which gold, copper, nickel, cobalt, and the platinum-group metals are produced as highly-pure metals to meet the exacting needs of the market. This book covers the scientific and engineering principles of these types of processes, the industrial practice used to produce such high-value metals, and the factors that make these processes so successful. In addition, the recovery of valuable metals through recycling of waste materials is discussed. For the user (why should he/she buy the book? A more scientific description of the book for the actual user/scientist/expert) This book describes the aqueous chemistry, thermodynamics, kinetics, reactor design and engineering of extracting metals by hydrometallurgical routes. The scientific and engineering principles for the processing of metals such as gold, copper, nickel, cobalt and the platinum-group metals from ores are presented. 1. Descriptions of individual unit operations, eg: Leaching, dissolution, digestion, electrowinning, electrorefining, solution purification, precipitation, solvent extraction A clear and thorough introduction of these topics is not available in one place for students or practitioners. 2.

Chemistry, modelling, and design of hydrometallurgical processes A quick reference in one place to the basics of hydrometallurgy 3. Design of flowsheets This is a topic that is not covered in academic studies, and an introduction on the methods of design a working process would be valuable.
