Desulphurization of hot metal is the most economic process for removing sulphur before charging to the BOF. Metallic Magnesium is the most effective reagent for desulphurization calcium oxide is the most cost-effective solution and the formed sulfides are very stable. Carmeuse provides fluidised milled lime, aimed at improving free flow and ... Nov 06, 2019 The results of determination of mineralogical composition of limestone, structural-phase transformations in the production of lime, iron ore agglomerate, and pellets with the introduction of limestone into the charge are given. The viscosity and refining properties of strontium-containing blast-furnace and steel-smelting slags are studied. 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.
