Cyanide Gold Extraction Methods. The existing cyanide gold plant in Chinas gold mines basically adopts two types of gold extraction process, one is a so-called conventional cyanidation process for gold extraction by continuous countercurrent washing with a thickener, and the gold is replaced by zinc powder CCD method and CCF.
native gold from gold-bearing ores. It has been known for more than a century that alkaline solutions of alkali-metal cyanides e.g., NaCN, KCN dissolve gold under aerated conditions. The dis-solution of metallic gold is due to the strong complexing capabilities of cya-nide anions combined with the oxidizing properties of the dissolved molecular
pulp for gold recovery. The rougher float tails may be further treated to recover gold that was not recovered in flotation, but which had been liberated from the old dumps by natural oxidation of some of the pyrite over many decades. The float tails would be neutralized and treated by cyanidation and CIL to recover this liberated gold.
In this case, the pyrite and arsenopyrite oxidation levels after 240 h of biooxidation were 65.7 and 94.1, and the gold recovery level was 71.7. View Show abstract
Jan 25, 2012 Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations.

The glittering golden mineral pyrite, an iron sulfide FeS 2, is known to most people as fools gold, something that promises great value but is intrinsically worthless.But pyrite is, has been, and will be important to you and the rest of humankind It is the mineral that made the modern world.
When the ore contains more sulfides, and the pyrite and gold ore are co-exist, pyrite can be extracted as a by-product. This type of gold may has different states. When the gold particle is coarse, simple grinding can extract the gold when the gold particle is fine and being wrapped by pyrite, it would be more difficult to extract.
Iron pyrite is a fairly common mineral, and is mined or extracted globally for its many industrial uses, such as extraction of the sulphur for sulphur dioxide or sulphuric acid, and also as an ore for iron. It oxidises readily, making it easy to extract the component minerals, but care must be taken as this also makes it quite combustible.
