摘　　要：对某金矿浮选尾矿进行碱浸预处理提金工艺研究,其试验结果表明:在磨矿细度-0.045 mm占95%、矿浆浓度50%、温度80℃、NaOH用量8 kg/t、预处理时间4 h,加入氧化剂的条件下,可获得70.11%的金浸出率。The paper studied alkaline leaching pretreatment process in recovering gold from tailings flotation in one gold mine. Results show that under such conditions as 95 % blow the grinding size of - 0. 045 mm, slurry density of 50 % , temperature of 80 ℃ , dosage of NaOH of 8 kg/t, pretreatment time of 4 h and with addition of oxidants, gold leaching rate of 70.11% can be obtained.
