05-05-2017· Manufacturing slag. Slag is a byproduct of smelting iron ore as part of the steel manufacturing process. Iron and many other types of metal ores found organically are impure and contain traces of other materials or metals. Heating iron ore in excess of 2,700 degrees Fahrenheit melts the metal and separates the pure iron from the impurities in

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H
