While limestone may seem unrelated to the production of iron and steel, it actually is an essential auxiliary material that is added during the production process. During the process of reducing iron ore, it is necessary to remove the silica, alumina (Al 2 O 3 ), and other non-ferrous components contained in iron ore. This relates to the Lebedinsky Mining and Processing Works as well. This results in certain environmental issues. Therefore the work provides the investigation results in some measure allowing the defined problem solution through complete replacement of limestone used for iron-ore pellet fluxing by the overburden chalkstone.

Dec 01, 2016 The commercial grade bentonite and limestone were used as additives in the pelletisation process. The iron ore pellets were prepared by using the raw materials of magnetite iron ore concentrate (100 m size), bentonite (75 m size) and limestone (100 m size). The detail chemical analysis of the raw materials is given in the Table 1 ... Oct 05, 2016 The per cent of iron in the ore as mined must be not less than 50%, if it is to be used without being first improved (beneficiated) by cobbing, washing, calcining, or magnetic concentration. Leaner ore is found in very large quantities and in a favorable situation, it may be workable by some concentrating process.
