that in this system the flotation behaviors of sphalerite and pyrite present irreversible characteristics along with the change of pulp potential. Furthermore, through the CDR system, considerable differences...%), is speedily reactivated after the pulp potential increases above 0.215 mV. Compared with the original mineral [1-2, 5], in the CaO depressing system, the flotation behaviors of pyrite or sphalerite......

. It is shown that the high floatability of galena with NNDDC as a collector is ascribed to anode oxidizing products. The range of optimum electrode potential in the flotation system was from the beginning... the potential is higher than 0.45 V. The recoveries of pyrrhotite and pyrite are marginal, and the recovery of marmatite is about 20%. Fig.5 Effect of potential on flotation of sulfide minerals in presence......
in the flotation process of chalcopyrite and pyrite was investigated through flotation experiments, zeta potential measurements and infrared spectrum analysis. Flotation test results indicate that DLZ... to chemical absorption onto chalcopyrite surface and only physical absorption onto pyrite surface.
