Developments in iron ore comminution and .
As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations. Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.

SAG Mill Grinding Circuit Design
Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.

Ore processing – Waihi Gold
Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
