Hydrometallurgical extraction and recovery of copper, gold ...

A hydrometallurgical process for treating copper feed materials containing gold and/or silver by simultaneously leaching copper, gold and/or silver into an aqueous cyanide solution, recovering copper in metallic form by electrowinning and regenerating cyanide ions is provided, wherein high current efficiencies are achieved at high current densities and at low copper concentrations.

Extracting Gold | HowStuffWorks

As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon. The carbon moves to a stripping vessel where a hot caustic solution separates the gold from the carbon.

What is Electrowinning? - wiseGEEK

An electrowinning unit consists of a large tank known as a reaction chamber. This chamber houses at least one set of cathodes, which are negatively charged electrodes, and anodes, which are positively charged electrodes.When the unit is turned on, direct current (DC) flows from the cathode to the anode through the liquid solution. The flow of electricity causes metals in the solution to plate ...
