Study on metallic mine's enlarging scale based on the equilibrium of mining,milling and smelting

In this paper, first, we explain the meaning of operation stratagems of the mining-joint-smelting enterprise. Second, we analyze the bases and conditions of the model. Third, we build up an economic mathematics model and solve it with GENOCOP algorithms. Finally, we interpret the model with a case and optimize different enlarging scales according to different operation stratagems, which provide definite guidance and consultant value to metallic mine's enlargement.
