Processing, smelting and refining gold

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.

Does Every River Contain Gold?

Does Every River Contain Gold? A placer deposit consists of gold flakes and sometimes small nuggets that can be sifted out of the sand by individual prospectors, mined commercially or used as an indicator of a nearby lode deposit. However, not every river has placer deposits or even gold deposits that are visible to the naked eye.

Cyanide

Aug 02, 2019On the path to commercialisation, we partnered with small gold producer, Eco Minerals Research, to build a mobile gold processing demonstration plant based in Menzies, Western Australia. The demonstration plant enabled us to trial and improve the process to ensure it was robust and practical at scale for commercial operations.
