Galena–Pyrite Bulk Flotation. The particle size has a significant effect on the flotation behaviors of minerals; therefore, the effect of grinding fineness (−0.074 mm) on galena -pyrite bulk flotation was firstly investigated and the results are shown in Fig. 2a. As can be noted that the recovery of lead, zinc, and sulfur was increased simultaneously as …

Abstract. Grinding and flotation experiments on a Pb-Zn ore were carried out to evaluate: 1) wear of the grinding media both in the presence and absence of an inhibitor and 2) effect of the inhibitor on the flotation of Pb Zn minerals. The percentage reduction in the wear of the grinding media was observed to be between 25–36%, depending on ...

For example, if sulphide minerals are reasonably abundant, if not dominant (cf. the Renison operation in Tasmania - cassiterite in pyrrhotite) so-called reverse flotation i.e. flotation of the sulphide minerals would be used. Otherwise, like floating scheelite and other oxide minerals, physical flotation with rather exotic collectors is required.
