Reducing grinding energy and cost — magnetite iron ore

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 associated with grinding was achieved over the

Mineral Comminution and Separation Systems

4. Comminution System To achieve the goal of recovering these concentr ates, the raw ore must be reduced to fine size prior to separation. This process is called 'comminution' or 'size reduction'. Generally there are two major objectives for comminution in mineral beneficiation: The first objective of comminution is 'liberation'.
