摘　　要：主要考察碱性硫化钠体系浸出高锑金精矿过程中金和锑的浸出行为,探讨浸出条件对金和锑浸出率的影响。试验目的是在保证锑浸出率的条件下,尽量减少金的浸出。试验研究表明,平衡金和锑的得失,在浸出温度50℃、时间1 h、液固比2∶1、硫化钠100 g/L、氢氧化钠10 g/L条件下,锑的浸出率可达91%左右;但同时金的浸出率也达到9%左右。Behavior of gold and antimony during leaching of Sb-bearing gold concentrate with sodium sulfide was studied, and the effects of leaching conditions on leaching rate of gold and antimony were discussed.The experimenters were supposed to reduce the gold leaching rate on the premise of guaranteed the leaching rate of antimony. The results show that under such conditions, leaching temperature 50 ℃ for 1 h, sodium sulphide of 100 g/L, sodium hydroxide of 10 g/L, liquid-solid rate at 2∶1, the leaching rate of antimony was about 91% accompanied with 9% leaching rate of gold.
