OverviewHistoryTypes of oreConcentrationLeachingRefractory gold processesGold smeltingGold refining and parting

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.

Gold Milling Process -Primitive and Basic

Here is an Ancient Gold Ore Milling Process used in China in the 1800s. We might use it again after WW3. At the time, 1890, the Author said “There is, of course, nothing for us to learn from this imperfect and rudimentary gold-extraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt

Gold processing Mining and concentrating Britannica

Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

IntroductionOre ClassificationComminution ProcessesProcess SelectionMill SizingConclusionReferencesOnce the gold ore has been removed from underground and brought to surface, an entirely new challenge begins in separating the gold from the waste material. The separation process is particularly difficult due to the usually low quantity of gold relative to waste. Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold content by weight. This means that upgrading the concentration by a factor of 3000 to 4000 is commonly required to achieve commercial ore (Marsden

Ore processing Waihi Gold

Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. The grinding process reduces the rock to a slurry. The SAG mill is a large revolving cylinder. Rock is ground by the turning action of the mill, and impact from the hardened steel balls and the rock itself.
