Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Usage: while being used, the noncyanide gold extraction reagent must be agitated with alkaline water at normal temperature, and then dissolved in a slurry to do gold leaching. In the process of heap leaching, pool leaching and CIP production of oxidized gold ore, the process is as same as the process of using sodium cyanide.
Thiourea Leaching of Gold. The use of thiourea for gold leaching has been proposed as a process alternative due to the supposed lower toxicity, faster leaching kinetics and the alleged less interference from base metals as compared to cyanide (Sparrow and Woodcock, 1995).

Jul 03, 2015· There have been several methods developed by miners to extract gold particles from ore over the last hundred or so years. Of those methods, the ''Cyanide Leaching Process'' (Cyanidation), is the method that is commonly used the most often to do this. As the name implies, the main component in the process is a sodium [.]
Introduction to Gold and Silver Leaching. The cyanide leaching process is the most important method ever developed for extracting gold from its ores. The early development of the process is attributed to a Scotchman, John Stewart Mac Arthur, in collaboration with the Forrest brothers. The method was introduced into South Africa in 1890.

This process of leaching is done in leaching tanks or by heap leaching where sodium cyanide is dripped onto a heap of gold ore and left to percolate its way ...
Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.
