This book gives an overview of all the gold extraction processes along with their mechanistic study and environmental impact. Different approaches in gold extraction are discussed including traditional pyrometallurgy, amalgamation, leaching by cyanide or non-cyanide lixiviants and emerging bioleaching using micro-organisms, in detail.
-
Reviews extraction techniques previously employed as well as recently evolved technology for gold leaching
-
Provides technical flow sheets for processing of ores with diversity of lixiviants
-
Offers a compulsory overview of every technique for gold processing
-
Discusses recent integrated techniques including hydro- and biometallurgical techniques with examples
-
Includes environmental imapct of each of the discussed technique
