Once the gold has been eluted, it undergoes a process called electro winning where the gold is precipitated, calcined and smelted in the existing smelthouse. The two eluate streams are kept separate to allow for accurate accounting of the gold produced by the respective high and low grade circuits.

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2 0.5 #181m of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.

The economic efficiency of the plant is assessed either by the net smelter return per ton of ore or the net revenue of the concentrator. The approach is illustrated for a lead silver gold plant located in Mexico and shows that the economic efficiency of this plant could be increased by 10 to 20%.
