Get PriceThese rather sudden ore feed grade changes can result in reduced flotation plant efficiency and hence losses in income. The prime objective of the project, to selectively recover and concentrate cobalt oxidized minerals by froth flotation, was not fully achieved on the ores tested.
Get PriceSome 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 nickelbearing iron sulphides which report to the flotation tails.
