Gold Refining From Gold Ore to Doré World Gold Council

2021-8-8  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.

Artisanal and Small-Scale Gold Mining Without Mercury US

2021-8-7  Artisanal and Small-Scale Gold Mining Without Mercury. In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant

SMALL SCALE GOLD MINING AND MARKETING IN

2011-10-4  In PNG, most of the gold deposits worked by small scale miners are alluvial deposits, in which the gold particles are liberated from the gangue particles. It is customary to use riffled sluice-boxes to recover the liberated gold particles. However, some of the gold particles, particularly the find gold, does not settle out in riffle compartments, and flow over to the discarded tailings. In the hope of catching some of these fine gold
