  • The Gold Smelting Process Melting, Smelting & Refining

    2017-1-18 · 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 a purity of about 99.5%.Process Of Refining Gold My Gold Guide,2018-5-15 · This process is known to purify gold to 99.95%. This method got its name from Francis Bowyer Miller, its inventor. In the Miller process, unrefined gold is first melted. Then, chlorine gas is passed through it. The gas turns other metals and impurities into a solid form, making it easy to separate them from gold.
