The invention discloses a column-
machine jointed segmental asynchronous rough concentrate regrinding and lead selecting method, which includes steps of A, performing ball-milling on raw ore by a ballmill and grading by a whirlcone; making the overflow enter a thickening pond to condense, and then floating the raw ore through a flotation
machine to rapidly select lead; B, after rapidly coarse selection of
gangue, making the rough concentrate to a vertical mill and then performing the ore
grinding work; grading the overflow by the whirlcone to condense by the thickening pond and then enter a flotation pillar to float and select lead. The method can preferentially select the silver lead mines which are easy to dissociate
monomer and float by the flotation
machine; then the
gangue is rapidlyselected to rough; after milling, the silver lead mines with complex distribution characteristics, fine grains and difficulty in
monomer disassociation can be floated from the rough concentration, thereby reaching the purpose of improving the
recovery of the silver lead. The method can simplify the selection flow, reduce the
energy consumption, improve the grade
recovery of silver lead concentration in the silver
lead zinc sulphide ore, improve the lead selection
recovery by 5%, improve the silver recovery in lead by 5%, and realize the high-efficient separation of silver and lead.
