摘　　要：叙述目前国内单槽容积最大的浮选机—200m3超大型充气机械搅拌式浮选机的带矿性能和工业应用效果,测定了浮选机的矿浆悬浮能力、对不同粒级矿物的分选效果、浮选机功耗、带矿条件下的充气量。试验结果表明200m3充气机械搅拌式浮选机矿浆悬浮能力好,槽内矿浆粒度分布均匀,没有粗、细颗粒分层现象,液面稳定。工业试验累计指标与对比流程指标相比:在给矿铜品位低0.001%的情况下,精矿铜品位低0.39%,尾矿铜品位低0.034%,铜回收率高6.77%,浮选效率高6.95%,系统回收率高0.92%,证明超大型浮选机浮选效果好。KYF-200m^3 air-forced flotation machine is the largest flotation machine in China. The working performance of KYF-200m^3 flotation machine in pulp is studied in this paper. The suspending ability, separation ability to different grade particle, power consumption and air superficia flow rate in pulp are also studied. The results show that the mineral particles suspend well in the cell, non- exsiting rough and fine layered phenomenon and the surface is smooth also. Comparing the average data ot test with another correlation mineral flotation series, the results are the following： copper grade of feed is 0.001% lower, copper grade of concentrate is 0.39% lower, copper grade of tailing is 0.034% lower, the recovery of copper is 6.77% higher, the flotation efficiency is 6.95% higher and the copper recovery of plant is 0.92% higher. The above indicates that the KYF-200m^3 performance is good.
