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

Get PriceAug 22, 2019 Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore
Get PriceJan 23, 2012 In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. It’s largely a matter of technology and requires much expertise and elaborate equipment. Mining for gold today can essentially be broken down into 9
Get PricePresent day placer mining uses pans, water and gravity, just like the prospector of 1849, only on a larger scale. This “modern” placer technology only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched
