中文摘要:
      脱硒渣浮选尾矿矿浆中含锑物料的沉降速率慢、沉降效果差是影响锑浸出率的重要因素,也是湿法冶炼锑工艺的技术难题。在浸出矿浆中加入絮凝剂沉降锑是工业上较为常用的方法,本研究以云南某企业的脱硒渣浮选尾矿为原料,研究了在含锑矿浆中加入不同的絮凝剂、以及絮凝剂加入量和温度等影响因素对浸出效果的影响。实验结果表明:与未加入絮凝剂的矿浆相比,改性阳离子型聚丙烯酰胺絮凝剂、改性阴离子型聚丙烯酰胺絮凝剂均能较大的提高矿浆的沉降速率,改性阳离子型聚丙烯酰胺絮凝剂在90℃,加入量为0.005g/L和0.006g/L之间时,絮凝沉降效果最佳。
英文摘要:
      The slow settling rate of antimony and poor settlement effect in the flotation of tailings slurry are the important factors affecting the leaching rate of antimony, and also a technical problem for the process of antimony smelting in wet process. Adding the flocculant to the leaching of antimony in the leaching pulp is the most commonly used method in industry. In this study, the effects of adding different flocculants in the antimony slurry and the influence factors such as the dosage and temperature of the flocculant on the leaching effect were studied in this study. The experimental results show that the modified cationic polyacrylamide flocculant and the modified anionic polyacrylamide flocculant can greatly increase the sedimentation rate of the pulp compared with the pulp without flocculant, and the modified cationic polyacrylamide flocculant is at 90 ℃, and the flocculation settlement of the flocculant is between 0.005g/L and 0.006g/L. The drop effect is the best.
