How Gold Is Mined | Gold Mining Process | World Gold Council

Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.

29-02-2016· The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching.

Gold Refining | From Gold Ore to Doré | 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.
