Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer miningsuch as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer m

Gold Extraction Recovery Processes - 911 Metallurgist

29-02-2016  Amalgamation is one of the oldest methods of extracting gold from its ores. The amalgamation of gold possibly dates from Roman times. The extraction of silver by amalgamation is generally attributed to the Spanish in Latin America in the late sixteenth century even though Biringuccio describes the fundamental principles of the “patio process” about a half a century earlier.

Gold extraction - QueensMineDesignWiki

The challenge of attaining economic extraction of gold from refractory ores is one of the main challenges in the mining industry today, as less refractory ores become more depleted. It is thus important to properly select an extraction method for refractory ores, based on mineralogy, precious metal grades, gold to sulphur ratios and hazardous impurities (Mark Aylemore, 2008).
