    gold ore cyanide process in sudan Shrawley

    Role of Cyanide in Ore Processing. A process called Cyanidation, or cyanide leaching, has been the dominant gold extraction technology since the 1970s. In this process sodium cyanide, in a dilute solution of ranging from 100 ppm to 500 ppm or 0.01 to 0.05 cyanide, is used to selectively dissolve gold from ore..Jan 01, 2005 This includes more pro-active cyanide management plans that inevitably involve a comprehensive understanding of the deportment of cyanide throughout the plant. The chapter provides a list of typical tests and procedures likely to be considered for a gold program. Cyanidation process has been the key element in the processing of gold ore.

    Since its inception in the late 1800s, cyanidation is the dominant process for the recovery of gold and silver from ores. Due to its simplicity and high cost efficiency, it replaced former processes nearly completely. Nowadays, the cyanide process accounts for more than 90 of primary gold.Oct 20, 2014 The Metallurgy of Cyanide Gold Leaching An Introduction. Leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. Despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
