Gold Leaching Leaching can be assimilated to the principle of preparation of tea. When we add tea in hot water, the aroma of tea will dissolve in the water and not the tea leaves. So the aromas is found in liquid form and tea leaves remains in solid form in the hot water.

The Metallurgy of Cyanide Gold Leaching  An Introduction

The Metallurgy of Cyanide Gold Leaching An Introduction

Oct 20, 20140183;32;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.

The new process also can be used to extract gold from consumer electronic waste. Current methods for gold recovery involve the use of highly poisonous cyanides, often leading to contamination of the environment. Nearly all goldmining companies use this toxic gold leaching

Cyanide Leaching Of Gold

Cyanide Leaching Of Gold

The cyanide solution strength is also important in leaching gold, with the typical range of solution being in the 0.02% 0.05% NaCN. The gold particle size has a tremendous effect on the time required for dissolution in a cyanide solution. Generally, the finer the gold, the quicker it will dissolve.

In simplified terms, the Effect of Oxygen on Gold Leaching can be summarized in saying The dissolution rate of gold in alkaline cyanide solutions under atmospheric conditions, and at practical cyanide levels, is directly proportional to the dissolved oxygen concentration.

Gold Extraction and Recovery Processes

Gold Extraction and Recovery Processes

Various methods such as gravity concentration, flotation, panning, pyrometallurgy, cyanidation etc are available for the extraction of gold metal from its ores. Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore.
