why limestone used in pelletising of iron

Effect of adding limestone on the metallurgical properties

Aug 10, 2015 Acid iron ore pellets with 4.6 wt.% SiO 2 manufactured by Severstal Resources in Karelia were used in the investigations. Both test pellets were produced in a laboratory-scale pelletizing drum and fired in sample baskets set in the middle of the sintering belt on the same production line as commercial blast furnace pellets.
