sulfur dioxide smoke produced commonly in our antimony smelters, the reducing-matting-smelting process, which is a new smelting process, was proposed. The effect of technical conditions such as smelting..., the direct and total recovery ratio of antimony is 87.02% and 97.79%, respectively, and the fixed ratio of sulfur is larger than 99%. Key words: stibnite concentrate; reducing-matting smelting; sulfur......
硫; 溶剂萃取 中图分类号:TQ136.1+2 文献标识码:A 文章编号: 1672-7207(2005)06-0994-07 Sulfur-retained in roasting process of molybdenite concentrate by pyrolusite FU Jian-gang, ZHONG Hong, WU Jiang-li, ZHANG Xiao-jun...-roasting was designed. The effects of material ratio between MoS2 and MnO2 on sulfur-retained ratio were investigated under the condition of temperature-gradient method roasting. The results show......
