How to Refine Gold: 2 Major Techniques of Process
Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

Electrorefining - Electrolytic Gold Recovery | Gold Refineries
Gold purity is typically 99.999%. Once the anode has been dissolved, the gold cathode can be removed, rinsed and melted into ingots. Unfortunately, the entire process can take a couple of days. For economical refining; often a different refining process, known as the Miller Chlorination Process, is used to separate gold to a purity of about 99.5%.

Ore Processing | OceanaGold - Waihi Operation - Waihi Gold
Ore processing is a 24 hour operation. Ore is stockpiled at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added to raise its pH. Following crushing through a jaw crusher, the ore is fed into the semi autogenous grinding (SAG) mill along with water and steel balls.
