lution concerns in the mining industry. Removal of overburden to access the ore can pose major problems in storage and reclamation. The over burden (waste to ore) ratio for surface mining of metal ores generally ranges from 2:1 to 8:1, de pending on local conditions. The ratio for solid wastes from underground mining is typically 0.2:1.

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or

01/01/2015· Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnacebasic oxygen furnace (BF BOF) routeor through the electric arc furnace (EAF) route. The majority of world crude steel is made from the BF BOF route.

23/10/2017· The Step by Step Process of Producing Iron from Iron Ore. Some 3000 4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).

31/12/2018· The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Hematite is an iron oxide mineral. It is non magnetic and has colour variations ranging from steel silver to reddish brown. Pure hematite contains 69.9% Fe by molecular weight. It has been the dominant iron ore mined in Australia since the early 1960s.
