gold mining elution and electrowinning

Electrowinning and Smelting - Resource Book

Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.

Elution and Carbon Reactivation - Resource book

The gold can then be removed from the solution by electrowinning onto steel wool cathodes (refer ‘Electrowinning and Smelting’ module). As well as stripping the gold from the carbon, the elution process incorporates an acid wash stage, which removes inorganic foulants from the carbon. Foulants reduce the activity, and hence
