The Chemistry of Gold Extraction is an extensively revised and comprehensively updated edition of the well-known reference first published in 1992. It provides the broad base of knowledge that is now required by all those working in the gold extraction and gold processing industries. The book bridges the gap between research and industry by emphasizing the practical applications of chemical principles and techniques. The technical reference includes in-depth discussions on: Historical Developments Ore Deposits and Process Mineralogy Process Selection Principles of Gold Hydrometallurgy Oxidative Pretreatment Leaching Solution Purification and Concentration Recovery Surface Chemical Methods Refining Effluent Treatment Industrial Applications16) Figure 5.7 shows the Eh-pH diagram for the S-H2O system. Thermodynamics predict that sulfur should be relatively easily oxidized to sulfate over a wide pH range, although the bisulfate species (HSO^) is formed below pH 1.5, anbsp;...
