The Mathematical Model in Optimization of Site Selection for Accumulated Bauxite

The mining programming of accumulated bauxite should comprehensively consider the site selection and rational utilization of resources. The mixed integer programming model on optimization of site selection and rational ore blending was constructed on the basis of the theories of logistics planning, operations research, etc. Take Taipingbei mine in Pingguo bauxite as the example, the results which were calculated by the operations research software Xpress-MP show that the model is rationality and feasible. The mathematical model is of great importance to the sustainable utilization of the bauxite resources, increasing mine service life and raising economic benefit of enterprises.
