Cyanide Process - Gold Cyanidation Process Gold

2018-10-19  Cyanide Process. Cyanide process is also called as Macarthur-forest Process. It is the process of extracting gold or silver from the ores by dissolving in a dilute solution of potassium cyanide or sodium cyanide. This process was introduced in the year 1887 by the Scottish chemists naming Robert W. Forrest, John S. MacArthur, and William Forrest.

Gold-Copper Ores - ScienceDirect

2016-1-1  1. Introduction. The association of gold and copper mineralization in commercially viable ore is a common occurrence. At one end of the spectrum is the predominantly copper ore, which contains levels of gold mineralization. This would be uneconomic to mine for its gold content, but the gold provides a significant opportunity value.

CYANIDE RECOVERY COST EFFECTIVENESS IS WHY

cyanide destruction and cyanide recovery costs for a fairly generic high cyanide-consuming case. The capital cost of a cyanide recovery plant could pay back in less than 2 years in many cases, particularly when high cyanide consumption is associated with copper mineralisation in the ore. As a broad generalisation, cyanide recovery
