Locating, extracting and processing these natural resources is a multiyear process that involves complex scientific, environmental and social planning. Newmonts mission is to build a sustainable mining business while leading in safety, environmental stewardship and social responsibility.
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 same tanks. CIL is slightly different from another gold extraction process called CIP or carboninpulp process.
Copper/gold ores that require uneconomically high quantities of cyanide to process due to the solubility of copper in cyanide. A multitude of other unfavorable constituents including pyrrhotite, tellurides,

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.
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver.
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.
The team at Charters Towers ensures the processing plant machinery is in satisfactory operational condition for the processing and extraction of gold from the ore. All equipment involved in the extraction process, including crushers, tanks and pumps is regularly examined for its durability and performance ability.

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
Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing lowgrade ore is relatively simple while higher grades require more extensive processing.
