Flotation of zinc oxide ores by cationic and mixed ...

2012-10-1  1. Introduction. The flotation of oxidized Pb and Zn minerals, particularly Zn minerals, is much more difficult than the flotation of corresponding sulfide minerals (Hosseini and Forssberg, 2007).The most common flotation technique used commercially for the treatment of ZnO minerals is sulfidization with Na 2 S, followed by treatment with conventional cationic collectors, namely amine

Influence of important factors on flotation of zinc oxide ...

2011-10-1  The influence of the pH adjusting reagent on zinc oxide flotation is shown in table 3. After adding 3000 g/t Na 2 S into the pulp, the given pH regulator was added to reach pH = 11. It is clear that using Na 2 CO 3 as a pH modifier can reduce both grade and recovery of zinc in the concentration while applying NaOH has desirable results.
