Rcovery of gold in pyritic ores - Mine Engineer.Com

2013-1-13 · The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite). The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound).

2021-2-21 · Commonly called fool’s gold, pyrite is the Earth’s most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore. Pyrite Uses

Selective flotation of gold from pyrite under oxidizing ...

The differential flotation of free gold from sulphide minerals can be interesting for both economic and environmental reasons. The use of hydrogen peroxide as an oxidizing agent in the selective flotation of gold from pyrite with potassium amyl xanthate was studied by contact angle and electrophoretic mobility measurements carried out under similar conditions.
