摘　　要：CCF浮选柱在铅锌矿选矿取得了良好的效果，以盘龙铅锌矿为例，一次浮选柱作业可以代替2～3次浮选机作业，选别作业由原来的18个分选作业减少为9个分选作业，最终获得的铅精矿中铅品位和回收率分别比原来高5．27％和0．54％，获得的锌精矿的中锌品位和回收率分别比原来高为2．88％和1．27％。CCF浮选柱在凡口铅锌矿同样获得了较好的效果，改造后采用的柱机联合流程比原来减少7个浮选作业，装机台数比原来少38台，且在品位基本保持不变时，采用柱机联合分选流程，可获得单一铅精矿和锌精矿，其回收率分别比原来提高19．56％和31．73％。The application of CCF flotation column in lead-zinc ore separation has reached good result.Taking PanLong lead-zinc plant for example, 1 CCF flotation column operation could re-place 2-3 flotation machine work, the separation processes reduced from 18 to 9.Compared with original indexes, the grade and recovery of lead concentrate increased by 5.27% and 0.54% re-spectively, which of zinc concentrate increased by 2.88%and 1.27%respectively.Good effect al-so obtained in FanKou lead-zinc plant.The flotation operations reduced to 7 by the combination of flotation column and flotation machine, and 38 machines were less than the original installed capac-ity, the grade of the concentrate was unchanged, single lead and single zinc concentrates were ob-tained through combined flowsheet, and the recovery of lead and zinc was improved 20%and 30%than before respectively.
