Iron Ore Smelting Process Bright Hub Engineering:
the ore is loaded into a blast furnace along with measured quantities of coke and limestone. hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. the iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. the slag and molten iron are tapped off from the bottom of the furnace, the slag being nickel ore deposits are closely associated with mafic and ultramafic in trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. thus the original source of most of the nickel ore bodies found in north america and elsewhere in the world was probably the mantle.the allentown firms innovation created a stir in iron making circles, and iron furnaces for smelting ore with anthracite began to appear across eastern and central pennsylvania. In 1841, only a year after the lehigh crane iron companys success, walter johnson found no less than eleven anthracite iron furnaces in operation.
