Abstract:
The understanding and application of autogenous (AG) and semi-autogenous (SAG) mills at various mines in China have been developing rapidly. A review of the application status of AG and SAG mills in metal mining operations in China is summarized in this paper. The SABC comminution circuit adopted for the first stage of Wushan copper-molybdenum mine project has been studied. Matching the equipment specification to the actual plant capacity, production instability and high energy consumption were the major issues at the Wushan SABC circuit. The operation status and energy distribution of each equipment were first analyzed and JKSimMet was then used to simulate the SABC circuit. Modifications and improvements including changing the grinding media filling ratio of SAG and ball mill, redesigning the pebble grate and adding pebble cabin have been performed based on the results obtained from simulations. A 36% increase in the designed mill throughput and a 2 kWh/t reduction in the energy consumption has been achieved through these modifications. It has been concluded that the optimization of SABC circuit using JKSimMet simulation can help increasing the throughput while reducing the energy consumption and can further be used for optimization of SABC comminution circuit at other mining operations in China.
