白银冶炼厂的炉渣贫化过程是高温下冰铜、炉渣和气相多次反应的复杂过程．本文将多元多相平衡算法和物理悬浮修正公式相结合，编制计算程序用于模拟白银冶炼厂炉渣贫化过程．计算得出在工业条件下底冰铜品位为４１．３３％，贫化渣含铜平均为０．４６９％，计算结果与工业数据一致．计算了鼓风量、黄铁矿用量对贫化效果的影响，结果表明贫化渣含铜受底冰铜品位影响，应控制底冰铜品位小于４７％，才能使贫化渣含铜降至０．５％以下．
The smelting process of silver smelter is a complex process of multiple reactions of matte, slag and gas at high temperature. In this paper, we combine the multivariate multiphase equilibrium algorithm with the physical suspension correction formula, and calculate the calculation program to simulate the slag depletion process in silver smelter. Calculated under industrial conditions, the matte copper grade is 41.33%, and the average copper content of depleted slag is 0.469%. The calculated results are consistent with the industrial data. The effects of blast volume and pyrite dosage on the depletion effect were calculated. The results show that the copper content in the depleted slag is affected by the matte grade, and the copper maturity should be controlled to less than 47% to reduce the copper content in the depleted slag to 0 .5% the following.
