  • Types Of Ores Check us out at An ore is a type of rock that contains minerals with important elements including metals. The ores are extracted through mining; these are then refined to extract the valuable element(s). The grade or concentration of an ore mineral, or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore. The cost of extraction must thus be weighted against the contained metal value of the rock to determine what ore can be profitably extracted and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or "native" metals (such as native copper) that are not commonly concentrated in the Earth's crust or "noble" metals (not usually forming compounds) such as gold. The ores must be processed to extract the metals of interest from the waste rock and from the ore minerals. Ore bodies are formed by a variety of geological processes. The process of ore formation is called ore genesis. Important ore minerals •Acanthite: Ag2S for production of silver •Barite: BaSO4 •Bauxite Al2O3 for production of aluminium •Beryl: Be3Al2(SiO3)6 •Bornite: Cu5FeS4 •Cassiterite: SnO2 •Chalcocite: Cu2S for production of copper •Chalcopyrite: CuFeS2 •Chromite: (Fe, Mg)Cr2O4 for production of chromium •Cinnabar: HgS for production of mercury •Cobaltite: (Co, Fe)AsS •Columbite-Tantalite or Coltan: (Fe, Mn)(Nb, Ta)2O6 •Galena: PbS •Gold: Au, typically associated with quartz or as placer ...
