Sodium Cyanide Market Growth, Trends, and Forecast

Sodium cyanide is sold either in liquid or solid briquette forms. It is extensively used in gold extraction, where the demand is majorly driven by the low costs and high availability. Another major factor driving the demand for sodium cyanide in the mining industry is that it is not self-combustible.

Sodium cyanide Wikipedia

Sodium cyanide is a poisonous compound with the formula Na C N.It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals.It is a moderately strong base.When treated with acid, it forms the toxic gas hydrogen cyanide:

How gold is extracted by cyanide process

<br> This takes place in metal drums with hard metal rods or balls. The most commonly used chemical for this process is Cyanide. As the cyanide and oxygen react chemically, gold in the pulp dissolves. The oxidant employed is atmospheric oxygen, which, in the presence of an aqueous solution of sodium cyanide, causes the dissolution <br> <br> Be on the lookout for your Britannica newsletter
