To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.

Step 5: Refining and Smelting. The eluate solution is pumped through electro-winning 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.

· Role of Fire Assay. Fire assay is the traditional and most common method for refining gold. This process involves heating the gold in a crucible to a high temperature, causing it to melt and separate from any other metals that may be present. The gold is then poured into a mold and allowed to cool, forming a solid bar.
