Geochemistry of Hydrothermal Ore Deposits
Here the mss is shown breaking into three segments near 200°C. Below 212°C±
13°C pentlandite-pyrite tie lines are established. An alternative interpretation of
the decomposition of the mss has been offered by McQueen (1979) and Cowden

Millerite, gersdorffite and nickelin have similar flotation properties as pentlandite.
These three minerals, however, are known to oxidize relatively fast in the
presence of oxygen. In general, nickel minerals are depressed with lime at a pH
9.5, the ...

This phenomenon would be observed in any mixed sulphide system as long as
elemental sulphur is a product of sulphide oxidation -such as those where
pyrrhotite is present. Furthermore, as pentlandite oxidation also produces
elemental ...

Applied Mineralogy in the Mining Industry
The results showed: • a high recovery of pentlandite (92 %) from the massive
sulfides, • negligible flotation of the various rock types from the barren rocks, •
dramatically reduced pentlandite recovery from ores containing massive sulfides
in ...
