Series: Process Metallurgy

Elsevier's Process Metallurgy book series is designed to provide a comprehensive source of detailed information on all aspects of Metallurgy.

The series aims to compile studies on novel processes, process design, chemistry, modelling, control, economics and interfaces between unit operations. Topics covered include: leaching of metal values by chemical reagents or bacterial action at ambient or elevated pressures and temperatures; separation of solids from leach liquors; removal of impurities and recovery of metal values by precipitation, ion exchange, solvent extraction, gaseous reduction, cementation, electro-winning and electro-refining; pre-treatment of ores by roasting or chemical treatments such as halogenation or reduction; recycling of reagents and treatment of effluents.
