pyrite rock in tin mining

Pyrite Mining | Processing Equipment | Flow Chart | Cases

What is 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 | Indiana Geological & Water Survey

Pyrite is a pretty mineral (Fig. 1) common to Indiana, but it also has a dark side. It is composed of iron (Fe) and Sulfur (S) with a chemical formula of FeS2. Atoms are arranged in an isometric crystal structure (Fig. 2) that makes cubic crystals. It shows a brassy, bright metallic luster when fresh, but readily tarnishes to dull surfaces upon exposure (Fig. 3A).

What is Pyrite? Pyrite is a brass-yellow mineral with a bright metallic luster.It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.

What is Pyrite? Why is pyrite a problem? | test

Pyrite or Iron Pyrite (FeS2) is a very common mineral that is present in many sedimentary rocks as framboidal crystals. Subject to certain conditions, pyrite is problematic in confined construction, such as under floor filling and bridge embankments. This is due to a chemical reaction that can cause pyritic backfill to swell.

Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scaly-foot gastropods. Despite being nicknamed fool''s gold, pyrite is sometimes found in association with small quantities of gold.

Rcovery of gold in pyritic ores

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).
