The Safe and Effective Use of Cyanide
Issue The family of chemicals containing “cyanide”, a combination of carbon and nitrogen, has been used safely and effectively for over 130 years for the efficient extraction and recovery of gold and silver from ore Cyanide is also used for a variety of other applications both within and outside the mining industryCyanidation is widely used by most gold mine worldwide and will remain prevail in years (or decades) to come, while cyanide is hazardous, toxic pollutants whose presence in wastewater and tailings can seriously affect human and its environment; hence, it is necessary to control these contaminants The purpose of this study was to examine theDecomposition of Cyanide from Gold Leaching Tailingsby UsingWith ores of higher gold content ( ie, greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators For extracting gold from lowgrade ores, heap leaching is practiced The huge heaps described above areGold processing Mining, Concentrating, Refining | Britannica
