【摘要】：针对广西大厂贫铟锡多金属硫化矿石因磁黄铁矿含量上升,铅锑品位下降,铅锑混浮捕收剂效果差,造成铅锑精矿指标不理想的问题,进行了磁黄铁矿弱磁选—铅锑混浮工艺条件研究。结果表明,磨矿细度为-0.074 mm占46.88%的矿石,经1次磁黄铁矿弱磁选(磁场强度为120 kA/m)后,以丁铵黑药+苯胺黑药+DY为组合捕收剂进行1粗2精2扫铅锑混合浮选,获得了Pb+Sb品位为55.08%,铅、锑回收率分别为93.22%、90.94%,锌含量为4.61%的铅锑混合精矿,与生产现场相比,铅锑混合精矿Pb+Sb的品位提高了2.91个百分点,铅、锑回收率分别提高了7.06、5.13个百分点,锌含量下降了0.58个百分点。因此,组合捕收剂丁铵黑药+苯胺黑药+DY可显著改善铅锑混浮精矿指标。
[Abstract]:In view of the problem of poor indium and tin polymetallic sulphide ore in Dachang, Guangxi, due to the increase of pyrrhotite content, the decrease of lead and antimony level and the poor effect of lead and antimony mixed flotation collector, the index of lead antimony concentrate is not ideal.The technological conditions of weak magnetic separation of pyrrhotite and mixed flotation of lead and antimony were studied.The results show that the grinding fineness is -0.074 mm accounting for 46.88% of the ore. After one weak magnetic separation of pyrrhotite (magnetic field intensity is 120 Ka / m), the mixed flotation of lead and antimony is carried out with the black butylammonium aniline DY as the combined collector.The Pb SB grade is 55.08%, the recovery rate of lead and antimony is 93.22220.94% and the zinc content is 4.61%. Compared with the production site, the grade of Pb SB is increased by 2.91%, the recovery of lead and antimony is increased by 7.06% and 5.13%, respectively.Zinc content decreased by 0. 58 percent.Therefore, the combination of ammonium butylammonium black aniline black drug DY can significantly improve the lead antimony mixed flotation concentrate index.
