Cumulative Recovery In Flotation

Nickel response.Figures 1 and 2 show how nickel cumulative recovery and grade varied with time during the flotation for the varying dosages of the copper sulphate added to the pulp.The overall consideration shows that at 15 gton copper sulphate dosage, nickel recovery improved clearly by a maximum of about 6 without grade compromise.
