Buy Sodium Cyanide online. Sodium cyanide is used mainly to extract gold and other precious metals in mining industry. This application exploits the high affinity of gold(I) for cyanide, which induces gold metal to oxidize and dissolve in the presence of air (oxygen) and water, producing the salt sodium gold cyanide (or gold sodium cyanide) and ...
Get PriceCyanide salts are used in metallurgy for electroplating, metal cleaning, and removing gold from its ore. Cyanide gas is used to exterminate pests and vermin in ships and buildings. If accidentally ingested (swallowed), chemicals found in acetonitrile-based products that are used to remove artificial nails can produce cyanide.

Get PriceCyanide is present in a number of compounds such as hydrogen cyanide, sodium cyanide, and potassium cyanide. (1) Hydrogen cyanide is a colorless gas or liquid with a faint, bitter almond odor. The odor threshold for hydrogen cyanide is 0.58 parts per million (ppm). (7)
[PDF]Get PriceOct 20, 2014 · Liberation: Cyanide leaching will only be effective if the cyanide can come in contact with the gold particle. For this to happen, the ore should either be sufficiently porous for cyanide to reach the gold, or more usually the ore is crushed and ground to a size at which the surface of the gold is exposed – i.e. the gold is liberated.
