Abstract: Realizing the existing issues that traditional empirical equations and Bond crushing work index are no longer fit for the reference basis of SABC circuit design and equipment sizing, an advanced simulation software JKSimMet was applied in this study to model the SABC comminution circuit of Wushan phase I copper-moly concentrator. The model was fitted and optimized based on the operation parameters. According to the simulation results the maximum throughput of Wushan SABC circuit is 850 t/h. The throughput of SABC circuit showed an increase of 26.7% after optimizing the operational parameters. Meanwhile, the comminution power consumption was decreased more than 2kW·h per ton, and the economic benefit was increased over 300 million yuan per year. Therefore, by using JKSimMet to simulate and optimize SABC circuit greatly increased the throughput and decreased the energy consumption. This result should shed some light on the domestic mining companies which are applying or plan to apply the SABC comminution circuit.
