· Refining gold is simply the process of removing the finer impurities that the smelting process could not remove. There are several methods used to refine gold. The most common gold refining methods include: 1. Miller Process . This is a chlorination process that refines gold to .
Gold Refining | From Gold Ore to Doré | World Gold Council
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it ...
How to Refine Gold From Electronic Scrap | Sapling
Mix a refining solution. Although you have recovered the gold from the electronics scrap, it may not be pure gold. It may be 12k or 18k gold, so now we will refine it to be pure 24k fine gold. Take a second beaker and pour it half full of Aqua Regina. Be very careful.

Silver Refining. The composition of silver dore bars the Perth Mint processes are composed of around 90% silver and 10% gold. As with gold dore, the silver dore is weighed, melted, assayed and outturned. The electrolytic silver refining process is similar to gold, except that the silver anodes are dissolved in a bath of nitric acid.
