Semi Autogenous Grinding Mill

As mined ore is typically less than 0.25 m in size.It is ground to a particle size of 80% passing 100 μm in a semi-autogenous grinding mill then sent on to leaching using sulfuric acid and sulfur dioxide under atmospheric conditions.A schematic flowsheet of this part of the process is shown in Figure 30.4.

Laboratory Grinding Mill

When the tube mill was first introduced, grinding was done in open circuit; i.e., the ore was ground to pass the limiting screen size by one passage through the mill. It was found, however, that if sufficient time of contact between the ore and grinding media were provided to ensure that no unground particles (or oversize) discharged from the mill, an excessive amount of fines were produced.
