The resulting liquid is collected at the bottom, and the gold is chemically extracted. Heap leaching extracts less of the gold than processing the ore in a mill, but is much cheaper. There are a few alternatives to cyanide for processing low-quality ores but none are employed very widely to date (1).
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.

Jul 22, 2019· A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold that is pure, but it does eliminate the bulk of the impurities.
The life cycle of mining begins with exploration, continues through production, and ends with closure and postmining land use. New technologies can benefit the mining industry and consumers in all stages of this life cycle. This report does not include downstream processing, such as smelting of ...
See our interactive gold mining map for gold production per country in 2016. Overall levels of mine production have grown significantly over the last decade, although substantial new discoveries are increasingly rare and production levels are increasingly constrained. Gold mining and mine production does not respond quickly to prices.

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 mercury ...
