The Norilsk-Talnakh ores contain about 7% nickel, copper and cobalt. In the Russian ores, palladium is more concentrated. All of the PGMs, except platinum, also occur in solid solution in pentlandite. Most of the Norilsk-Talnakh ore is passed through centrifugal density separators before proceeding to froth flotation.

How to Extract Nickel From Copper-Nickel Sulfide Ore?

For the froth flotation process of copper-nickel sulfide ore, the collector and foaming agents of copper sulfide ore are often used. A basic principle for determining the froth flotation process is to make the copper into the nickel concentrate and avoid the nickel into the copper concentrate as far as possible.
