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 …

Reducing grinding energy and cost — magnetite iron ore design case …
Efficiency of the comminution operations is traditionally assessed based on operating cost and energy consumption. Traditionally, the lowest operating cost was achieved by multi stage fully autogenous grinding due to elimination of steel grinding media costs which may represent up to 50 % of the grinding cost. Significant reduction of the cost …

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.
