The entire process of gold mining can be broken down roughly into four steps: prospecting, mining, extracting and refining. Early discoveries of gold relied on the blind luck of someone spotting a yellow glint in a stream or in a crack between rocks. But the search today is more systematic and precise. First, geologists know more about how gold ...

The final stage of gold production refining involves removing impurities that remain after the smelting companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or ...

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.

Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth''s crust. It occasionally is found as nuggets as large as 12 millimetres ( inch) in diameter, and on rare occasions ...

Though Gold is not the primary product, this mine produces more Gold than any other mine in the world. The final category of gold mining is the processing of Gold ore. This method is largely becoming deprecated as the yield of Gold is often very low and the environmental impact .

Mineral Processing Golden Mile ore is of two main types: weathered oxide ore from near the surface which is freemilling with the gold easy to extract, and sulphide ore in deeper ore bodies where the majority of the gold is locked as inclusions in tellurides and pyrites and is difficult to extract.

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 percent purity. The Wohlwill process increases purity to about percent by electrolysis.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carboninleach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in .

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process.
