Features and Flotation of Complex Cu-Pb-Zn Sulphides

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 .
