Uses. Iron is the world's most commonly used metal, and iron ore is a key ingredient for steel making. To produce 1,000 kilograms of crude steel requires about 1,400 kilograms of iron ore (and around 800 kilograms of coal). Iron can be alloyed with a variety of elements to produce stronger and harder products which are useful in the

19.07.2019In MOE processes, iron ore is dissolved in a molten oxide mixture at 1823–1973 K (1550–1700 C). The anode, made of a material inert towards the oxide mixture, is dipped in this solution. Electrical current is passed between this anode and a liquid iron pool connected to the circuit as the cathode.

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
