Sodium cyanide is an inorganic 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.

Sodium cyanide in gold mining - libra-nh.Sodium cyanide in gold min.Sodium ferrate was prepared using a self-made electrochemical device and the effects of the ph and ferrate dosage used in the preparation on the cyanide,cu2,and ni2 removal rates from electroplating wastewater by the prepared ferrate were investigated.
Sodium cyanide is the most commonly used leaching chemical in gold extraction process.According to theoretical calculation, leaching 1 gram of gold only requires 0.5 grams of sodium cyanide.However, in most gold cyanidation plants, the consumption of cyanide is high, which is 50-100 times higher than the theoretical calculation.
The international cyanide management code for the manufacture, transport, and use of cyanide in the production of gold cyanide code was developed by a multi-stakeholder steering committee under the guidance of the united nations environmental program unep and the then-international council on metals and the environment icme.
The key difference between sodium cyanide and potassium cyanide is that sodium cyanide is produced via treating hydrogen cyanide with sodium hydroxide, whereas potassium cyanide is produced via treating hydrogen cyanide with potassium hydroxide.Sodium cyanide and potassium cyanide are mainly used in gold mining though they are highly toxic compounds.
Acids should not be used around sodium cyanide or potassium cyanide unless absolutely necessary and then only after careful planning.Hydrogen cyanide hcn formation is the greatest potential hazard in using sodium cyanide or potassium cyanide solutions because some.
