Mt. Keith ore. 16.4 Flotation of copper–nickel ores. As stated earlier, the type of pyrrhotite present in the ore and flowsheet play an important. role in selecting reagents for copper–nickel flotation. There are two basic flowsheets prac-ticed in treatment of massive sulfide copper–nickel ores. These include (a) removal of mon-

04.11.2013Decades of research have shown that the basic mechanisms of particle collection in the pulp and froth zones of a flotation machine are different based on size and liberation of the ore particles. As a result, using large vessels as roughers is a compromise since some ore particle types are recovered more efficiently at the expense of other types.
