Methods Of Gold Mining Geology In

Other gold mines use underground mining, where the ore is extracted through tunnels or shafts. South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air.

Gold Smelting & Refining Process

Feb 28, 2016 In general, some elements and compounds form fine disperse centers where the crystallization starts. Silicon is not very soluble in gold and silver. In this way, a low melting eutectic point is produced which modify the melting point of the alloy. Normally the compound is formed on grain boundaries making the alloy a little brittle.
