摘　　要：某含砷金精矿含毒砂矿物较多，砷质量分数达6．12％。该精矿直接用氰化炭浆工艺处理时，金的浸出率为58．36％；经助浸剂预处理6～8h后，氰化过程中加入防膜剂及活化剂SmD，金的氰化速度加快，浸出时间缩短8～10h，浸出率可达到91．2％。The arsenic content in a certain gold concentrate is 6.12%. With direct cyanidation CIP technology process, the extraction rate of gold is 58.36%. After pretreatment with leaching aid agent for 6 - 8h, the cyanidation rate of gold is enhanced obviously with film-prevention reagent and SmD activator added in cyanidation process. Meanwhile, the gold extraction rate is 91.2% and the extraction time is cut by 8 - 10h.
