Step 5: Refining and Smelting. The eluate solution is pumped through electrowinning reactors where gold is plated onto cathode steel mesh or wool. (Electrowinning is a process of recovering metals from a solution by passing a current through it). The plated gold is then washed off and dried in cylinders called calciners, inside heated furnaces.

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfidecontaining gold ore with high floatability. In addition, the flotation process is also used for polymetallic goldbearing ores such as goldcopper, goldlead, goldcopperleadzincsulfur ore.

Carbonin leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain pregrobbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon.

A final "polishing" stage occurs in the third step, where hydrogen peroxide is added at neutral pH. Thickened sludge is disposed of to the tailings pond. A conceptual process flow chart is shown in Fig. 5. The Hemlo process can generate a treated effluent containing less than mg/L total cyanide and metal ions.
