Effect of limestone and dolomite flux on the quality of ...

2021-2-1  The present work illustrates the effect of limestone and dolomite as flux material in pelletization of an Indian goethetic-hematite iron ore with 59.75% Fe, 4.52% SiO 2, 3.84% Al 2 O 3, and 4.85% LOI. As per mineralogical analysis, this ore contains 30.11% goethite and 9.71% kaolinite, which contribute major LOI of the sample.

Effect of adding limestone on the metallurgical properties ...

2015-8-10  In general, the main types of pellets for the purposes of making iron are acid, basic and fluxed. In order to produce high-quality pellets, certain additives are important. The most common fluxing materials for iron ore pellet production are limestone (CaCO 3), dolomite (Ca,Mg(CO 3) 2) and olivine (Mg 2 SiO 4), but sometimes magnesite (MgCO 3 ...
