Cyanide Use in Gold Mining - Earthworks

The cyanide dissolves the gold from the ore into the solution as it trickles through the heap. The pad collects the now metal-impregnated solution which is stripped of gold and resprayed on the heap until the ore is depleted. Vat (or tank) leaching: The ore is mixed with cyanide solution in large

sodium cyanide process for gold process -

Sodium gold cyanide. It is used in mining for extraction of gold and other expensive metals. Gold being a least reactive metal shows a high affinity for cyanide, causing it to oxidize, and dissolve in the presence of oxygen and water. Sodium gold cyanide and sodium hydroxide are the respective products of this extraction process.

Extraction of gold using cyanide - NZQA

Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble. To make gold soluble sodium cyanide (NaCN) is added and the

Hydrometallurgy - Wikipedia

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy.

Electroplating that uses cyanide in the plating bath which

cyanide in the bath works to dissolve the HAP metal added as a cyanide compound (e.g., cadmium cyanide) and creates free cyanide in solution helping to corrode the anode. These tanks are self regulating to a pH of 12 due to the caustic nature of the cyanide bath chemistry. The cyanide in the bath is a major bath constituent and not an additive. However, the self- regulating chemistry of the
