摘　　要：贵州某高砷含金硫化矿石金品位2.10 g/t、砷品位5.86%,含金矿石以砷黄铁矿、磁黄铁矿和毒砂为主。对该矿进行了可选性试验研究,在磨矿细度为-0.074 mm占65%的条件下,经过一粗三扫三精闭路试验,可获得金精矿产率11.83%、金品位16.52 g/t、金回收率90.23%的较好试验指标。A high--arsenic gold--bearing sulfide ore contains Au 2.10g/t and As 5.86% in Guizhou, gold-- bearing ore mainly exist in form of rnispickel, pyrrhotite and arsenopyrite. An investigation was made of the flotability of the ore, on the condition of grinding fineness as --0. 074 turn was 65 %, by adopting closed--circuit process of one--stage roughing, three--stage cleaning and three--stage scavenging, prefer ably test indices as gold concentrate rate of 11. 83%, Au grade and recovery of 16. 52% and 90. 23%can be obtained.
