Why is Iron Ore Valuable? Iron ore is a rock from which the metal iron is extracted. About 98% of the world's iron is used to produce steel.. Pure iron is an element and a soft grayish-white metal. Other than meteorites that fall from the sky, iron is never found by itself in nature.
Jan 01, 2012· Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 5.3.7 Manganese Ore. Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions.
Jul 07, 2017· Limestone is also a very important industrial mineral. Its chemical properties make it a valuable mineral for a wide range of industrial/manufacturing uses. Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight.

Sep 23, 2019· Limestone then creates the slag. Impurities such as S, Si pass into the slag and the slag later can be easily separated to yield pure iron. The iron minerals that are used as ores are hematite, magnetite, limonite, and siderite. Hematite is the most important iron ore. Extraction of iron .
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.

Jan 08, 2017· Limestone is used in iron extraction to remove impurities from the iron and becomes molten slag. The calcium carbonate (CaO3) in limestone catabolically reacts, forming calcium oxide(CaO) and carbon dioxide(CO2). CaO is highly reactive when subjec...
Iron is extracted from its ore, haematite, in a blast furnace. The ore is fed into the top of the furnace along with coke and limestone. ... The limestone decomposes in the hot furnace, forming calcium oxide. This reacts with the sandy impurities (silicon dioxide) to form a slag.
A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
Steelmaking requires iron ore, metallurgical coke which is also called coking coal and limestone as input ingredients, out of these three essential raw materials India is self-sustaining on iron ore and limestone whereas about 85% of coking coal requirement of the domestic steel industry is .
The limestone is added to the iron ore burden of the blast furnace in the amount of ~117kg per tonne of "hot metal" (steelmaker's slang for the liquid iron produced by the blast furnace). This produces the slag of 181kg per tonne of hot metal which contains most of the impurities: 38% SiO2, 36% CaO, 14% MgO, 9% Al2O3, plus minor amounts ...
