gold extraction by cynide process

Silver and gold are extracted by the cyanide process (Mac Arthur - Forrest process). After the preliminary crushing and concentration by froth floatation process, the ore (crushed auriferous rocks in the case of gold) is leached with dilute (0.4 - 7%) solution of sodium cyanide made alkaline by adding lime kept agitated by a current of air

gold cyanidation

Cyanide 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

Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal. Chemically, it is a rather simple reaction: 4 Au + 8 (NaCN) +O2 + 2 H2O = 4 NaAu (CN)2 + 4 NaOH
