    Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.
