Ore Grinding

Ore grinding is a process to further reduce and disperse the ore particle size. In the mineral processing industry, ore grinding is the particle size preparation before the separation of the crushed ore. Except those that process some placers, almost all mineral processing plants have grinding operations, in which materials are crushed by …

The largest reduction in throughput in AG milling (45%) was observed for the softest ore (GAL-IF) operating in closed circuit, which could be explained by the inability of the ore to perform as autogenous grinding media, given its fineness (Fig. 4) and low competence (Table 4). This was also the ore associated with the largest increase in SSE.
