Semi Autogenous Grinding Mill an overview

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.
