The kinetics modeling of chalcopyrite and pyrite, and

ABSTRACTIn this study, a series of batch flotation experiments was conducted to evaluate both the role of particle size distribution and the presence of sodium metabisulfite Na2S2O5 (SMBS) in chalcopyrite and pyrite flotation. Kinetic flotation tests were also carried out in order to evaluate the kinetics behavior of the above-mentioned minerals.FUNDAMENTAL STUDIES ON PYRITE, PYRRHOTITE,Pyrite,pyrrhotite and arsenopyrite are sulphide minerals which bear iron in their structures and are collected in flotation plants byWO1993010904A1 - Flotation separation of arsenopyrite from,,A collector is added promoting flotation of pyrite, preferably a xanthate, more preferably sodium isobutyl xanthate, and the pulp is subjected to a pyrite cleaning froth flotation, as indicated by Py cleaner in Figure 1, in the conventional manner.
