Ways to Recover Gold from Cyanide Heap Leach Solutions
Ways to Recover Gold from Cyanide Heap Leach Solutions

Gold recovery from alkaline cyanide solution is typically accomplished by carbon adsorption or zinc cementation (Merrill Crowe). These and other emerging technologies, particularly resin ion exchange, solvent extraction, and direct electrowinning, are discussed, emphasizing the unique features of each process alternative.

cyanide can be regenerated as free cyanide for recycle to the gold recovery process. This improves cyanide utilization efficiency and mitigates copper presence in tailings. Additionally, copper recovery generates an incremental revenue source to further improve project economics.

The Metallurgy of Cyanide Gold Leaching  An Introduction
The Metallurgy of Cyanide Gold Leaching An Introduction

Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed i.e. the gold is liberated.

Gold Recovery from Molybdenum Concentrate by Cyanide Leaching
Gold Recovery from Molybdenum Concentrate by Cyanide Leaching

Gold and silver average 8 and 40 ppm respectively which at an average molybdenum concentrate production of 10 tonnes per day translate into an annual potential of approximately 950 ounces of gold and 4700 ounces of silver. These preliminary calculations indicate that silver recovery was of marginal value to this project.

Gold cyanidation
Gold cyanidation

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.
