Gold recovery techniques from cyanide solutions. CN process can be used for removing gold from gold plated electronic waste like connectors, fingers, jewellery and any other stuff which has gold polish on it.
The slurry (1) of ground ore and lime moves into a series of six leach tanks (2) where a sodium cyanide solution is added. The tanks provide sufficient retention time to allow the gold and silver to be dissolved by the cyanide solution.

Through reaction with the ore, the cyanide leaching solution, typically sodium or potassium cyanide, forms an aqueous solution of a cyanide-gold complex.¹
Before the cyanide process was introduced, although the assay value of the quartz at Martha Mine was reasonably high, gold recoveries were low.
Amalgamation has been used for thousands of years to recover small sized or fine gold. Historically, it was used in many operations to increase gold recovery.
