remember that only 0 67 of the ore is copper the copper minerals and waste rock are separated at the mill using froth flotation the copper ore slurry from the grinding mills is mixed with milk of lime simply water and ground-up limestone to give a basic ph pine oil yes it comes from trees -- a by-product of paper mills
apr 4 how by flotation would you separate sulphide rock with 8 pb 9 zn 0 3 cu and 3 5 mn? do you think it would be possible to produce 4 different and clean penalty free concentrates? any possibility to make a manganese a zinc a lead and copper concentrate any smelter/refinery will buy?

separating minerals by floatation the flotation process can separate a required mineral such as copper nickel molybdenum or zinc from ore flotation can separate this the cyclone overflow continues on to a series of floatation cells that separate the plants typically add lime to the slurry in the mill or floatation circuit
both quicklime and hydrated lime are widely used in the flotation or recovery of many non-ferrous ores -- in particular copper ore flotation in which lime acts as a depressant settling aid and in thermal reduction techniques magnesium oxide from dolomitic quicklime is reduced with ferrosilicon at high temperatures
