The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 2014· Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

Cyanide Leaching Of Gold Mine Engineer.Com

Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores. And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal.

Processing, smelting and refining gold World Gold Council

In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore

The process design of gold leaching and carbon-in-pulp

African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation. The ore is first reduced in size (typically 80% passing 75µm) to ensure that all non-refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the

Natural Source of Cyanide in Plants eHow

Many common plants contain the natural form of cyanide, cyanic glucoside. Its presence may be the product of evolution, as it deters animals and insects from consuming the entire plant. Most animals can tolerate digesting small amounts, but during drought, the amont of the chemical in plants increases.
