Mining equipment for Pyrite processing

Gravity separation that can process pyrite is the separation that is according to the proportion difference between the pyrite and gangue which is associated with pyrite. The specific gravity of pyrite is higher and the specific gravity of gangue is lower. Through crushing and grinding, intergrowth structure in pyrite will be destroyed.

Pyrite Minerals Education Coalition

Pyrite. 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: The Real Story Behind “Fool’s Gold”

Pyrite is a widespread natural source of arsenic, which can leach into ground-water aquifers when geologic strata containing pyrite are exposed to the air and water, during coal mining for example. Acid mine drainage and groundwater contamination requires close monitoring to ensure that it has been neutralized before being returned to the earth.

Ask The Experts How do I recover gold in pyrite? ICMJs

A: It’s true that pyrite from gold mines will contain a small amount of gold. It is microscopic and is found inside the pyrite crystal. Miners who process gold ores will get free gold particles that can be melted into bars, but they also recover pyrite that has small amounts of gold within it.

Rcovery of gold in pyritic ores Mine Engineer.Com

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).
