<p>A bulk concentrate containing chalcopyrite, pentlandite and pyrrhotite is aerated under alkaline conditions, then subjected in turn to primary flotation, cyanide addition, conditioning, secondary flotation and cleaning flotation. As a result, a three-way separation is achieved to produce a copper concentrate, a high grade nickel concentrate and a third product containing most of the pyrrhotite.</p> |
