Extracting Gold HowStuffWorks
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.

How Gold Is Refined: A Step-By-Step Guide Pease Curren
The crude gold is melted and then treated with chloride. This converts any foreign elements or minerals still in the gold into chloride, which will then naturally drift off the gold. The result of this process is 99.5 percent pure gold. The final step is to cast the gold into electrodes or anodes and place them in an electrolytic cell.
