摘要: 旋流-静态微泡浮选柱的混合充填是在筛板充填的基础上引入蜂窝管充填的一种充填模式,目的是比筛板充填进一步弱化旋流力场对柱分选的负面影响。采用混合充填旋流-静态微泡浮选柱和筛板充填旋流-静态微泡浮选柱在云南某硫化铜进行半工业分流试验,结果显示,两者都可以大大简化工艺流程和节省药剂用量,但混合充填旋流-静态微泡浮选柱的铜精矿品位和回收率比筛板充填旋流-静态微泡浮选柱分别高2.28和1.18个百分点,从而证明了混合充填的有效性。

Abstract: The mixed packing with cyclonic static micro-bubble flotation column is a packing mode of honeycomb tube packing based on sieve plate packing,arming to further weaken the effect of cyclone field on the column separation.The mixed packing and the sieve plate packing with cyclonic static micro-bubble flotation columns were used to separate Yunnan copper sulfide in a semi-industrial test respectively,and the results showed that both could shorten the flotation technological flow-sheet and save the dosages.However,the grade and recovery copper concentrate in mixed packing was higher by 2.28 and 1.18 % respectively.Thus the efficiency of the mixed packing is proved.
