Gold is found in very low concentrations in the ore from which it is mined. Iron cyanide complexes are especially stable and are important due to large.
Sodium cyanide is also used in New Zealand to produce a cyanide paste for opossum control. A complex cyanide, prussian blue, is used for dyeing jeans.
more complex gold ore bodies, which is usually accompanied by higher levels of cyanide consumptions and greater concentrations of cyanide particularly.
which for example, the cyanide complexes of copper and nickel are detrimental to the recovery of gold by zinc precipitation. 2 The carbon granules are added
