Turning Cyanide into Gold: Sodium Cyanide Applications in ...

The application of zinc separates the cyanide molecules from the gold and turns the gold back into a solid, readying it for the smelting process. Is Mining With Cyanide Chemicals Safe? Like any commercial chemical, sodium cyanide and other mining chemicals are as safe as their handling process.

why sodium cynide is used in zinc mining – Grinding Mill

While the use of cyanide is essential to the modern gold mining industry, SME acknowledges the public's concern regarding the use of this reagent and , copper, zinc and silver represents approximately 15% of cyanide consumption globally, with the remaining 85% of cyanide , The concentration of cyanide used in this process averages approximately 0025% sodium cyanide (250 parts per million) [2]

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:

Should cyanide still be used in modern-day mining?

Toxic sodium cyanide has been used in gold mining since 1887, and it remains the primary reagent in use for gold processing today because it allows for efficient extraction of gold from low-grade ore. Since a tailings dam burst at gold mining company Aurul’s Baia Mare mine in Romania in 2000, leaking cyanide into the Somes River and killing large ...

VERVIEW OF CYANIDE TREATMENT METHODS

In the mining industry, cyanide is primarily used for extracting silver and gold from ores, but cyanide is also used in low concentrations as a flotation reagent for the recovery of base metals such as copper, lead and zinc. At these operations, cyanide treatment systems may be required to

Gold cyanidation - Wikipedia

The basic ore slurry can be combined with a solution of sodium cyanide or potassium cyanide; many operations use calcium cyanide, which is more cost effective. To prevent the creation of toxic hydrogen cyanide during processing, slaked lime ( calcium hydroxide ) or soda ( sodium hydroxide ) is added to the extracting solution to ensure that the acidity during cyanidation is maintained over pH 10.5 - strongly

Cyanide Destruction Methods and Processes

The reaction is typically carried out at a pH of about 9.0 to 9.5 for optimal removal of cyanide and metals such as copper, nickel and zinc. However, if iron cyanide must also be removed to low levels, then the pH is lowered somewhat to increase the precipitation of copper-iron-cyanides at the expense of lowering the removal efficiencies of copper, nickel and zinc.
