Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on Earth, and is widespread in rocks and soils.[5] Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
Some common uses of copper:
As a result of its excellent electrical conductivity, copper's most common use is in electrical equipment such as wiring and motors. Because it corrodes slowly, copper is used in roofing, guttering, and as rainspouts on buildings. It is also used in plumbing and in cookware and cooking utensils.
