Gold mining

Gold mining is the resource extraction of gold by mining. As of 2017, the world's largest gold producer was China with 429.4 tonnes. The second largest producer, Australia, mined 289.0 tonnes in the same year, followed by Russia with 272.3 tonnes.

Gold extraction

Gold extraction

This is typical of low grade, oxide deposits. Normally, the ore is crushed and agglomerated prior to heap leaching. High grade ores and ores resistant to cyanide leaching at coarse particle sizes, require further processing in order to recover the gold values. The processing techniques can include grinding, concentration, roasting, and pressure oxidation prior to cyanidation.
