division of geology and mineral resources zinczinc is a bluishwhite, lustrous metal with the chemical symbol zn. its main ore mineral is sphalerite (zns). some of its uses are for galvanizing (plating thin layers of zinc onto iron or steel to protect from corrosion), production of brass (combination of zinc and copper), and coloring in rubber and paint. of first production in ia 70s.main differences between ore and mineral you should knowthe most widespread ores are iron ore, aluminum ore, g ore, lead ore, zinc ore, manganese ore, and many others. ore is an economic term for valuable rock. all ores are essentially composed of minerals. all ores are minerals, but not all minerals are ore. ore minerals and gangue minerals make up the ore.ores and minerals introduction, extractionwe get minerals and ores in abundance in the earths crust. some ores have been proven themselves a great resource for mankind. such as iron obtained from ore of iron (hematite) built the foundation of industrial revolution. out of total naturally occurring elements 70% are metals. metals occur in nature in free as well as in combined states.zinc ore and mines minerals and mines foundations ofoverviewcrystal habit and structurepropertiesvarietiesdeposit typesusessee alsoexternal links
sphalerite ((zn,fe)s) is a mineral and ore of zinc. when the iron content is high, sphalerite is an opaque black variety called marmatite. it was discovered in 47 by ernst friedrich glocker, who named it based on the greek word "sphaleros" meaning deceiving due to sphalerite being hard to identify. sphalerite is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite and fluorite. miners have been known to refer to sphalerite as zinc blende, blackjack and · text under ccbysa licensephotos of natural zinc ore, zinc minerals and specimensthe zinc minerals are zincite, franklinite, sphalerite, smithsonite, willemite, hemimorphite, and goslarite. zinc minerals heated on charcoal give an encrustration, which is yellow when hot, white when c, and which, if moistened with cobalt nitrate and strongly reheated, assumes a fine green color.mineral resource of the month zincjan , · sphalerite, a zinc sulfide mineral, is the primary ore mineral for zinc and has been the source for most of the worlds production. u.s. and world mine production of zinc credit k. cantner, agi. world mine production of zinc, by country, in estimated reading time 2 mins
