The gold grade of a gold ore from Shanxi is 2.33 g/t.The gold minerals are disseminated with non-uniform distribution of coarse and fine particles.According to the property of the ore,study on the joint process of flotation and gravity separation was carried out.Finally,it was decided that the process of flotation-gravity separation of flotation tailings be used.Under optimal test conditions,good indexes were obtained,for example,the gold grade in the gold concentrate is 40.59 g/t,gold recovery rate is 89.13 %,the total recovery rate of flotation+gravity separation is 93.69 %,providing technical references for efficient utilization of ores.
