1. Introduction. In comparison to conventional tumbling mills, i.e., rod- and ball mills, the grinding media in an autogenous mill derive from the feed ore itself (Rowland and Kjos, 1978).Any change in feed ore properties will therefore affect the grinding charge and thus, the breakage mechanisms within the mill.
An autogenous or semiautogenous circuit, as the name implies, uses the ore itself to assist in the grinding process. Generally, for this type of circuit, the ore must be competent so large ore chunks can be used to grind smaller ones.
