摘要：The refractory stibnite used in this research is from Shan yang, Shaanxi. The ore characteristics are coarser grain size of the stibnite, which is favorable for flotation. But the clay minerals (kaolinite and illite), pyrite and arsenopyrite in the ore will bring some difficulties to flotation. Through on the research of the slurry regulator, stibnite collector and gangue mineral inhibitor, better flotation index was obtained. Under the condition of the Sb raw ore grade 2.25%, the flotation index of the concentrate contains Sb 65.12% with the recovery of 91.56%, and the arsenic content of 0.20 was obtained.
