一般采用混合-优先浮选流程，如图4.2所示。将矿石磨到-0. 074mm为60%~80%。先混合浮选锑金(砷)，得混合精矿，然后进行锑金(砷)浮选分离，采用硫化钠-碳酸钠法来抑制辉锑矿，浮选金(砷)，经两次精选得金(砷)精矿，槽内产物为锑精矿;混合浮选的尾矿经扫选，扫选的泡沫产物给入锑金(砷)浮选分离系统，槽内产物再经过一次锑粗选、 一次精选、一次扫选， 得成品锑精矿和废弃尾矿，中矿返回锑金(砷)混合浮选的扫选作业。渣浆泵厂家
What is the scum slurry pump separation method for antimony gold polymetallic sulfide minerals?
Antimony gold polymetallic sulfide ore is produced in the meso low temperature hydrothermal cleft filling antimony gold intergrowth deposit, the main mineral is stibnite, followed by natural gold, antimony sulfide lead ore, antimony oxide, chalcopyrite, pyrite, arsenopyrite, etc. Gangue minerals are mainly quartz, followed by mica and silicate. Stibnite is mostly dense and massive. The natural gold is in the form of irregular particles, and gold and arsenopyrite are closely related.
Generally, the mixed priority flotation process is adopted, as shown in Figure 4.2. Grinding the ore to - 0.074mm is 60% ~ 80%. Flotation of antimony gold (arsenic) is first mixed, then antimony gold (arsenic) is floatated and separated. Sodium antimony carbonate is used to inhibit stibium ore and flotation of gold (arsenic). Gold (arsenic) concentrate is picked up by two times, and antimony concentrate is selected as the product in the tank. After flotation of the tailings, the foam product is swept into the antimony gold (arsenic) flotation separation system, and the product in the tank is once again selected by antimony roughing once. The final antimony concentrate and waste tailings are obtained by cleaning and one-time scavenging, and the middle ore is returned to antimony gold (arsenic) mixed flotation. Slurry pump manufacturer
Flotation agent: in the mixed flotation of antimony gold (arsenic), the pulp pH is adjusted to 6.5. Xanthate and black agent are used as the mixed collectors, lead nitrate and copper sulfate are used as the mixed activators. In the flotation separation of antimony gold (arsenic), the pulp pH is adjusted to 11-12, and sodium sulfide and sodium carbonate are added as the adjusters.
