Author Description

To compensate for increasing prices, it is imperative that gold be recovered from primary as well as secondary sources, and from saturated solutions employing new approaches. This book gives an overview of all the gold extraction processes along with their mechanistic study and environmental impact. Gold extraction involves different approaches including traditional pyrometallurgy, amalgamation, leaching by cyanide or non-cyanide lixiviants and emerging bioleaching using micro-organisms, which are discussed in detail. Key Features, Reviews extraction techniques previously employed as well as recently evolved technology for gold leaching, Provides technical flow sheets for processing of ores with a diversity of lixiviants, Offers a compulsory overview of every gold processing technique, Discusses recent integrated techniques including hydro-and bio-metallurgical techniques with examples, Examines the environmental impact of each technique discussed Book jacket.
