Processing, smelting and refining gold World Gold Council

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 produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

Gold extraction - Wikipedia

Gold occurs principally as a native metal, usually alloyed to a greater or lesser extent with silver as electrum , or sometimes with mercury as an amalgam .Native gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles known as color embedded in rock minerals.

9 Step Process for Discovering, Mining and Refining Gold

Step 6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step 7 – Processing on-site Once ore is extracted, processing it into pure gold must be done.
