Alibaba offers 710 gold cyanidation products. About 36% of these are other mining machines, 9% are leaching tank, and 1% are cyanide cyanate. A wide variety of gold cyanidation options are available to you, such as free samples.
Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide quot;vat leachingquot; mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock.

LEACHING GOLD SILVER ORES WITH SODIUM CYANIDE AND THIOUREA UNDER COMPARABLE CONDITIONS By J. A. ~isele,' A. E. ~unt,~ and D. L amps shire^ ABSTRACT There is currently mch interest in how extraction of gold and silver from ores with acidic thiourea solution compares with extraction using alkaline cyanide solution.
Cyanidation, or the metallurgical process of extracting gold from ore with cyanide leaching agents, has long been a primary method of gold beneficiation. Widely used throughout the world, one incredible material helps to make gold recovery from a cyanide solution possible; with its ultra porous structure, activated carbon is a powerful adsorbent used throughout a number of industries to separate material

that preferentially absorbs the gold cyanide complex but not the gold thiosulphate complex), it can yield substantially better recovery than cyanide. The thiosulphate leaching of gold ores has great potential to reduce the impact on the environment compared to the cyanidation process. Unlike cyanide, which is
The gold is mixed with the sodium cyanide which leads to the following Elseners equation and reaction. This is done to make soluble gold; Now the gold is soluble. This method of making soluble gold is known as leaching. In the process of leaching, dilute form of sodium cyanide is added into the ore containing the gold.
Gold reacts with sulfides to form thiocyanates, renderring the cyanide useless to gold leaching. Thiosulfate is all together different chemistry, and not nearly so interesting to cyanide consumption.
