Gold Mining with Cyanide

Gold Mining with Cyanide Some 90 percent of gold mines around the world employ "cyanidation," the use of a sodium cyanide compound to separate the gold from finely ground rock At a gold mine in Romania in , the accidental release of 100,000 cubic meters of cyanide-rich waste into the local watershed killed all aquatic life in nearby waters and cut off water supplies for 25 million peopleBecause cyanide leaching is very efficient, it allows profitable mining of much lower ore grad Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold.

Extracting Gold

Removing the gold-bearing rock from the ground is just the first step To isolate pure gold, mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller piec At a mill, large machines known as crushers reduce the ore toPlacer mining is the technique by which gold that has accumulated in a placer deposit is extracted Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.

Use in Mining

Cyanide is manufactured and distributed for use in the gold and silver mining industries in a variety of physical and chemical forms, including solid briquettes, flake cyanide and liquid cyanideCyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock This process usually takes place inside a mill or other mining facility.
