The mineral processing simulation software aims to realize the simulation calculation of different ore dressing process and is a powerful tool for design and optimization of ore dressing process.In the paper,the simulation model of mineral processing is given,the automatic solving method of sequential modular approach for simulation calculation is described,the system partition method based on reachability matrix method is introduced,and then,according to process topological structure,the ring break method based on breadth-first searching of directed graph is proposed.The design idea of mineral processing simulation software based on sequential modular approach is described,which is applied to grinding-classification process in the ore dressing plant of some nonferrous smelting enterprises.The simulation results from the software are essentially in agreement with the measurement results,which verify the effectiveness of the software.
