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.
