iron pyrite copper

Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. The Copper Iron Sulphide is again a compound used as a friction material in a number of industries.The large quantities and widespread distribution of chalcopyrite make it the leading source of copper.

Iron pyrite is unstable at Earth's surface: iron pyrite exposed to air and water decomposes into iron oxides and sulfate. This process is hastened by the action of Acidithiobacillus bacteria which oxidize the pyrite to produce ferrous iron and sulfate. These reactions occur more rapidly when the pyrite is in fine crystals and dust, which is the ...

Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.

The term pyrites is applied to any of a number of metallic sulfides that strike fire with steel. Some minerals resembling pyrite in appearance or composition are arsenopyrite, chalcopyrite (copper pyrites), cobaltite, marcasite (white iron pyrites or spear pyrites), and pyrrhotite (magnetic pyrites).

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.

If sufficient iron is not available from the sand and pyrites, more can be added using red iron oxide. Using additional Iron Pyrite to increase the iron is not recommended, as this will add too much sulphide and create an unstable glass.
