Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
The Bond BMWI has no correlation with the throughput or power requirements of a SAG Mill. Should be carried out on samples from each ore domain and in conjunction with a full JK Drop Weight Test for correlation purposes. The SMC Test requires significantly less sample than the JK Drop Weight Test or JK Rotary Breakage Test.
of grinding media led to adoption of SAG and FAG flow sheets in certain iron ore plants recent developments in the understanding of blast through mill size reduction call into question the actual economies of SAG/FAG mills. Figure 2 compares blast energy to electrical consumption in the SAG mill.
