Features and Flotation of Complex CuPbZn Sulphides

Abstract. Problems arising during flotation of complex Cu-Pb-Zn sulphide ores are in general of geological origin. The features of these ores are reviewed, stressing that mineralogical studies extending to process mineralogy are prerequisite for a consistent flotation process. Some examples affecting flotation are given.

US5439115A Process for selective flotation of copper

In a process for a selective flotation of a copper-lead-zinc sulfide ore the raw ore is ground and slurried with water and the resulting suspension is aerated with air to adjust a certain oxidation-reduction potential and is subsequently successively conditioned with SO 2 , CaOH 2 , and collecting and frothing agents, whereafter a flotation of Cu is effected.
