A copper lead and zinc polymetallic ore from Xinjiang belongs to refractory low-grade polymetallic sul-fide ore. The raw ore grade of Cu is 0. 15 %,Pb 3. 52 % and Zn 1. 24 % respectively. According to ore properties,a process of mixed flotation of copper and lead-separation of copper and lead-zinc recovery from copper and lead tail-ings-magnetic separation of iron from zinc tailings is employed,obtaining a copper concentrate with copper grade of 22. 30 % and recovery rate of 68. 63 %,and a lead concentrate with lead grade of 58. 67 % and lead recovery rate of 86. 83 %,and a zinc concentrate with zinc grade of 42. 85 % and recovery rate of 65. 32 %,as well an iron concen-trate with grade of 67 . 0 % and recovery rate of 62 . 97 %( recovery rate by magnetic separation is 97 . 52 %) . The closed circuit has all products meet the requirements of national standard quality.
