3). Thus, the gold particles are in electrical contact with that electrode. Since secondary electrowinning may also be carried out simultaneously in that cell, the gold from both sources is effectively combined at the cathode. However, initially the EWEF cell was used on its own to electrowin gold from original and diluted eluate solutions.

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.

The process has the potential of achieving significant gains in hygiene, environmental controls, and efficiency for the refining aspect of primary lead production. Also attractive about the granulationleachingelectrowinning process is that it could decouple the smelting furnace from refining operations.
The gold is recovered from this solution by electrowinning, zinc precipitation or refining technology such as the Mintek Minataur process. The eluted carbon may still contain various organic 48 2 4 4Au NaCN O H O NaAu CN NaOH+++ → + 22 2 The process design of gold leaching and carboninpulp circuits
