Facts about Gold

Ore samples are taken and examined for the metallurgical quality of the gold in order to determine the appropriate processing technique required to remove the gold. The mine site infrastructure includes a processing area where the ore is crushed and undergoes various processes depending on the nature of the associated minerals and then the loose rock is sent to the appropriate processing location.

Gold: The mineral native Gold information and pictures

To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods. Gold nugget s, a popular form of Gold with collectors, are formed when erosion causes a large piece of Gold to separate from its mother rock, and then gets carried into a stream or river. Get price

Gold

Because ore grades of 30 ppm are usually needed before gold is visible to the naked eye, in most gold mines the gold is invisible. The average gold mining and extraction costs were about $317 per troy ounce in 2007, but these can vary widely depending on mining type and ore quality; global mine production amounted to 2,471.1 tonnes.
