Limestone – Its Processing and Application in Iron and ...

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.

Development on Iron Ore Pelletization Using Calcined

However, suitable adjustment of flux composition and process parameters can make the calcined lime usable in pelletization as advantage. This study is concentrated on optimization of MgO (olivine) flux addition and basicity and finally used calcined lime in place of limestone in developing good quality iron ore pellets with combined flux.

METALLURGICAL USES FLUXES FOR METALLURGY

2016-3-4  the world is iron and steel (Anon., 1991a, Habashi, 1986), and consequently, use of flux is preponderantly in the iron and steel industry. In the United States, metallurgical flux required by both the ferrous and nonferrous industries is abundant, and most of the demand is satisfied by domestic production with the exceptions of
