Mining and mineral processing | The lithosphere ...
Processing the gold ore (ESBRM) For every ton of ore that is mined, only a very small amount (about (text{5}) (text{g})) of gold is extracted. A number of different methods can be used to separate gold from its ore, but one of the more common methods is called gold cyanidation. In the process of gold cyanidation, the ore is crushed and then cyanide ((text{CN}^{})) .

The Gold Smelting Process
· The first step in gold smelting involves processing the gold ore. The ore containing gold once mined from the earth is processed by separating gold minerals from the crude matter holding the ore together. The gold ore is then pulverized using pressure to create very fine particles. These fine particles are then heated in a furnace to temperatures above 1064 degrees Celsius the melting point .

(PDF) Gold Extraction and Recovery Processes For Internal ...
In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized. The reagents used for flotation are .

Roasting and Refractory Gold Ore
· Gold''s resistance to oxidation is a critical point of most refining and extraction methods, and the roasting process is no exception. During roasting, refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize, separate from the ore, and become sulfur dioxide. Once all of the sulfides are oxidized, the remaining gold ore can be processed .

The Mining Process
Alternative Ore Processing. We use alternative gold recovery methods in some processing plants to accommodate different ore characteristics or other requirements. For example, ore that has a high level of sulfide minerals or carbon (or both) is called refractory ore. Refractory ore resists normal processing methods as the high sulfide minerals trap gold particles, making it difficult for the ...
