  • Selection oof Comminution Circuits for Improved Efficiency

    circuit (crushing, stockpiling and grinding) representing 35% and 50% of plant capital cost for the 1 Mt/a and 20 Mt/a plants, respectively. Comminution costs include power, grinding media and maintenance materials. These costs represent 30% of costs for the 1 Mt/a plant and over 50% of costs for the 20 Mt/a plant. Thus, the “efficiency” of a modest plant is improved by simplifying the

  • Grinding Circuit an overview ScienceDirect Topics

    The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]). This type of flow sheet is usually followed when the crude ore contains below 30% iron

    A standard crushing and grinding circuit is shown in Figure 1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher (SABC). This circuit shows a semi-autogenous grinding (SAG)/ball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of ‘critical size’ material in the circuit. ‘Critical
