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
