The report identifies the cyanide and acid wastes associated with the extraction or concentration of metals from ores. The cyanide-bearing wastes covered are related to keep and vat leaching operations in the gold and silver industries. The wastes generating sulfuric acid are found in several metal mining sectors. However, the report focuses on the operations using surfuric acid (largely generated from iron sulfides) to leach copper from dumps and estimates the acid generation potential for will tailings accumulated in impoundments.
