The leaching and adsorption behaviour of gold ores

gold was completely extracted by cyanide alone. The flotation feed and copper concentrate showed an enhancement in gold extraction due to the activated carbon adsorbing gold that would otherwise have been preg-robbed. However, this effects. Get price

What is Gold Cyanidation? (with picture)

2020/5/16The process of gold cyanidation is usually conducted in an outdoor setting, though an indoor facility, that meets safety regulations, is sometimes employed. A cyanide salt, such as potassium cyanide, sodium cyanide, or calcium cyanide, the most popular choice, is mixed with water and then applied to the ore. Get price

Processing, smelting and refining gold

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 and solvent in large tanks equipped with agitators.
