| description | The invention discloses a sedimentation method for high-fineness flotation of copper concentrates from copper smelting furnace slags. When concentrate slurry precipitates, nonionic polyacrylamide andpolymeric aluminum are added, and the copper concentrates suspend on the upper part of a concentrate concentration basin and are difficult to clarify and separate as the particle size of the copper concentrates is small. The flocculating agent sedimentation and separation method is adopted, the copper concentrates rapidly settle in the concentrate concentration basin, rapid clarifying and separation of copper concentrate overflow water and the copper concentrates are achieved, the phenomenon of mudflow of the overflow water in the concentrate concentration basin is solved, and the slag concentration and grinding-flotation procedure is conducted continuously.
本发明公开了种铜冶炼炉渣高细度浮选铜精矿沉降方法，在精矿浆沉淀时，加入非离子聚丙烯酰胺和聚合氯化铝，由于铜精矿粒度较细，铜精矿悬浮在精矿浓缩池上部分，难以澄清分离，采用本发明絮凝剂沉降分离的方法，使铜精矿在精矿浓缩池内快速沉降，达到铜精矿溢流水与铜精矿快速澄清分离，精矿浓缩池溢流水"跑浑"现象得到解决，渣选磨浮工序 |
