gold extraction calaverite

Calaverite Wikipedia

Calaverite, or gold telluride, is an uncommon telluride of gold, a metallic mineral with the chemical formula AuTe 2, with approximately 3% of the gold replaced by silver.It was first discovered in Calaveras County, California in 1861, and was named for the county in 1868.. The mineral often has a metallic luster, and its color may range from a silvery white to a brassy yellow.

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 mining such as simple gold panning and sluicing, resulting in direct recovery of

Gold Extraction an overview ScienceDirect Topics

The effect of pH value on gold extraction for various ore types is shown in Figure 28.4. Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH 9.5–10.0, whereas for some carbonaceous ores, pH value has no apparent effect. However, the outcome will vary depending on the nature of the gold and background mineral matrix
