Copper Nickel Bulk Flotation

Copper-Nickel ores - Danafloat

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. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small ...

Copper-Lead-Zinc ores - Danafloat

In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation minerals. Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation from the bulk flotation tails.
