Thermodynamic modeling of lead blast furnace TAN Peng-fu(谭鹏夫) (Mount Isa Mines Limited, Queesland 4825, Australia) Abstract: A thermodynamic model was developed to predict the distribution behavior of Cu, Fe, S, O, Pb, Zn, As, and the heat balance in a lead blast furnace. The modeling results are validated by the plant data of a lead smelter in Kazakhstan. The model can be used to predict......
