Effect of adding limestone on the metallurgical properties

2015-8-10  One example is Umadevi et al. (2011), who carried out basket trials with iron ore pellets with basicity ranging from 0.08 to 1.15 in order to understand the effect of adding limestone on the microstructural, physical and metallurgical properties of iron ore pellets. In their study, the Tumble Index (TI) and the Cold Crushing Strength (CCS
