dc.description.abstractAbstract Cyanidation uses solutions of sodium or potassium cyanide as leaching agents is usually used to extract gold metal from its ore. The cyanide process for extracting gold was an improvement over the inefficient mercury amalgamation process that was used previously, which usually do not recover more than 60% of gold content in the ore. Using cyanide for the recovery of gold was first developed in Scotland in the late 19th Century. There are two ways to leach gold using cyanide: Vat leaching and Heap leaching. In 1998’s approximately 70% of gold had been recovered using vat leaching, and only 30% using heap leaching. Now cyanide leaching is used over 90% of the flee milling gold. The Technique used in gold mining industry today includes heap or valley leaching. Agitation leaching as Carbon in pulp (CIP) Carbon in leach (CIL). In some cases, leaching is followed by carbon in columns CIC alter solution filtration fiom the pulp. Cyanidation as such is the best to suit, fine grain disseminated gold deposits. Although cyanide is hazardous to the environment, it is widely used in gold mining & extraction industry in the world. Gold mining industry uses only 14% of the total amount of the produced cyanide. Cyanide is safe and easy to use conditioned that proper management, according to intemational cyanide code, which includes using of drip irrigation and uses of optimum Impermeable insulators such as (Polly Vinyl Chloride (PVC), Poly Ethelene High or low densityen_US
