Limestone is used mainly in the iron, The production of iron or steel is a process, Open hearth steelmaking means the pig iron, more iron ore and limestone [Chat Online] Limestone Used In Production Of Sponge Iron The process of manufacturing sponge iron or DRI is known as DR process Liquid hot metal and solid pig iron would also be .
Apr 30 2011 #183; Sponge Iron vs Pig Iron Sponge iron can be produced by direct reduction of iron ore through reducing agents whereas pig iron is produced by melting iron ore with charcoal and limestone at very high pressures Pig iron is soft and brittle because of high carbon content but is used to make wrought iron and steel that are extremely useful
is limestone used in the production of sponge iron primus process for sponge iron production. The direct reduction process generates metallic iron in the solid form i e sponge iron or DRI which is used chiefly for the EAF steel production The smelting reduction process serves to produce of the hot metal These proces ses are highly important to the EAF get price

7/7/2017#0183;#32;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. There can be small particles of quartz (silica), feldspar (aluminosilicates), clay minerals, pyrite (iron sulphide), siderite (iron carbonate), and other minerals associated with the limestone.
Sponge iron is a product produced using iron ore that''s often used for making wrought iron and the gases processing for iron production India. Process for
limestone used in production of sponge iron advantages of limestone in sponge iron process. advantages of liTONne in sponge iron process The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnaceThe key principle is removal of impurities from the iron by oxidation with air
