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.
