Process Of Extracting Silver From Ore

Silver is extracted from the ore-argentite (\(Ag_2S\)). The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide \(Na [Ag(CN)_2]\). Silver Ore The Mining Processes that Transform

Cyanide Process Of Gold Extraction

In the cyanide process for extraction of gold and silver. 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.
