Hydrometallurgy of Precious Metals: Effects on the Environment
Abstract Factors which affect the release of toxic substances to the environment during the hydrometallurgical processing of precious metals bearing ores are discussed. The experimental work and industrial results on the following aspects of the cyanidation process, having environmental notions, are surveyed. Chemistry of cyanidation and generation of an environmentally hazard compounds. Process selection and preparation of leach pads. Methods for treatment of process solutions. Effluent characteristics with a view of wastewater treatment options selection. Long and short term fate of cyanide in environment — regeneration and destruction. Environmental impact and risk assessment procedures. The review of new work, in the field of alternative gold lixiviants is also presented and attention is drawn on the degree of toxicity of these lixiviants.
