On a Russian CuPbZn ore good selectivity against galena and sphalerite was obtained in the flotation of bornite and chalcopyrite as a high grade copper concentrate. Stagewise grindingflotation with three grinding steps were used to obtain reasonable liberation of .

CuPb mixed concentrate regrinding process saves the grinding cost without fine grinding all the ores are, and it makes further monomer dissociation to create favorable conditions for the separation of .

Initial flotation tests indicate the deposits are amenable to a common flotation flowsheet with the sequential CuPbZn flotation flowsheet providing the best overall performance for all four deposits tested. Further development of the sequential flotation by bench scale testing is in progress.

Flotation is the most widely used in separating sulfide PbZn ore, to separate zinc and plumbum, sometimes for separating sulfide iron and other minerals . Sulfide PbZn ore process divides into priority flotation process, mixseparating flotation, asynchronous flotation,and so on .It is a high technological enterprise that integrated research, manufacture, sales and service .

Common Flotation Flowsheet – Initial bench scale batch flotation tests were designed to compare two flowsheet options: 1) a bulk Cu/PbZn flotation flowsheet and 2) a sequential CuPbZn flotation flowsheet using various reagent schemes and alternative grind specifications.
