Direct Reduction Process

This is a coal-based reduction technology, applicable to both steel mill waste and iron ore fines, with coal as a C-reductant agent. The reduced iron can be fed to a BF or directly into a melting process. If exposed to air for a long time, the metallic iron reoxidizes into iron oxide, deteriorating its quality.

Electric Smelting Furnace of Ore

The largest furnace that Electric Smelters has built is smelting 100 tons of iron ore in Norway (per day, presumably). This was erected in 1916 but is not mentioned in Millers report of 1936 cited later. The smallest furnace has a capacity of 750 pounds in 24- hours and is employed for reducing precipitates.

Iron Ore

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm.

Copper Production: How Is Copper Made?

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
