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.

The first step in oxide gold ore processing is the mining of the ore itself, followed by the primary crushing of the gold containing rocks. This step is important because it helps to simplify the material for further processing in other steps. The smaller ore pieces are then transported to a ball mill after the first crushing.
Gold processing steps: 1. Wet crushing and washing. The raw gold ore is fed evenly into the trommel screen using a vibrating feeder. High-pressure water is used to wash the ore, breaking down clay and mud while cleaning it thoroughly. Large ore pieces are discharged from the back of the screen, while smaller pieces go to the jig.
