中文摘要:
      为了回收含锑金精矿中的锑,减少锑对两段焙烧过程的影响,对浮选富集得到的含锑金精矿进行硫化钠碱性浸出锑研究。优化实验表明,在液固比1.5:1 (mL/g),氢氧化钠用量20 g/L,硫化钠用量40 g/L,反应温度80℃,浸出30 min,锑浸出率可达98%以上。在此基础上,采用焙烧炉余热将电解贫液加温至80℃,对液固分离方式、锑电积阴阳极板和冷冻结晶装置进行工艺改造,使锑的浸出率>98%、阴极锑纯度>95%,日产锑量增加17.35%。
英文摘要:
      In order to recover antimony from antimony concentrate bearing gold and reduce the influence of antimony on the two-stage roasting, the antimony gold concentrate after flotation enrichment has been studied by alkali sodium sulfide leaching. The results showed that the leaching rate of antimony is more than 98% by applying a liquid solid ratio of 1.5:1, 20 g/L of sodium hydroxide, 40 g/L of sodium sulfide, leaching 30 min at 80℃. For the lean electrolytic liquid, the leaching rate of antimony was more than 98% after it was heated to 80℃ by using roaster waste heat and treated by a modified separating method of liquid and solid, reforming anode and cathode plates of antimony and adding a freezing crystallization device. The purity of the resulted cathode antimony was more than 95%, and the daily production yield increased by 17.35%.
