Pyrite Mineral Uses and Properties

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 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.

TaconiteMinnesota DNR

The taconite pellets are brought to the steel mills to be melted down into steel. Taconite is mined from the Mesabi Iron Range, near Hibbing, MN. Then it is processed into pellets and moved by train--or on ore boats from Duluth--to ports and steel mills around the Great Lakes region.

processing of ore to get pure metals

How do you get pure metals from metal ore Answers. Metal ore is a type of rock from which metal can be extracted. Metal ores are normally oxides for example, aluminum is the most common metal in the Earth's crust, but in order to get as pure aluminum as possible, it needs to be extracted from an ore.

How do we extract minerals?USGS

The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock. Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods.
