The invention discloses an arsenic-sulfur separation method for arsenic-tin-lead-zinc-antimony polymetallic ore. The arsenic-sulfur separation method comprises the following steps: (1) recycling pyrrhotite in zinc tailings through magnetic separation; (2) carrying out arsenic-sulfur separation on the pyrite and the arsenopyrite through a flotation process to obtain arsenic concentrate of sulfur concentrate; and (3) fine silt tin possibly existing in the arsenic concentrate is subjected to gravity separation (table concentrator) to obtain micro-fine particle tin concentrate. By the adoption of the method, sulfur, arsenic and tin minerals in the lead-zinc flotation tailings can be comprehensively recycled, comprehensive utilization of resources is achieved, tailings discharge is reduced, and environmental pollution is relieved. 一种砷锡铅锌锑多金属矿的砷硫分离方法，包括如下步骤：(1)针对锌尾中的磁黄铁矿通过磁选进行回收；(2)针对黄铁矿和毒砂通过浮选流程，进行砷硫分离，得到硫精矿的砷精矿；(3)针对砷精矿中可能存在的细泥锡通过重选(摇床)得到微细粒锡精矿。采用本发明能够对铅锌浮选尾矿中的硫、砷、锡矿物进行综合回收，实现资源综合利用，减少尾矿排放，减轻环境污染。
