Cyanide Use in Gold Mining - Earthworks

Cyanide's efficiency makes mining more wasteful. Because cyanide leaching is very efficient, it allows profitable mining of much lower ore grades. Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used;

Gold and silver typically occur at very low concentrations in ores - less than 10 g/t or 0.001% (mass basis). At these concentrations the use of aqueous chemical (hydrometallurgical) extraction processes is the only economically viable method of extracting the gold and silver from the ore. Typical hydrometallurgical recovery involves a leaching step during which the metal is dissolved in an .
