Complex Processing of Refractory Pyrite Copper, Copper-Zinc and ...
At the beginning of the ore flotation, the copper "head" liberates. With the return of cleaning tailings in the ore flotation, the sphalerite is flotated out of the chamber product. This reduces the circulation of the pyrite-pyrrhotite intermediate products circulation significantly. An important problem is the presence of tennantite in some ores.

FROTH FLOTATION : RECENT TRENDS Flotation of Sulphide Ores - HZL Experience
FLOTATION PROCESS Flotation is a method of separating an ore species froth another, based on its hydrophobic surface characteristics either natural or induced when present as a suspension in water with air bubble. Due to the affinity of the desired mineral to adhere to air bubbles it is floated out of the ore slurry.
