· 1. Introduction The flotation process is a separation technique primarily used in mineral processing for the recovery of minerals (Wills and Finch, 2016), that also finds application in other industrial processes such as wastewater treatment and paper recycling (Saththasivam et al., 2016, Vashisth et al., 2011).).

Gravity separation has been used for centuries to separate different minerals and metals based on their specific gravity. Some of the earliest recordings of this science in practice are from Ancient Egypt as workers panned for gold in the Nile river. While today’s geology enthusiasts still pan for gold in streams, Sepro has taken the science

Abstract In this research, flotation of copper, lead and zinc minerals from a copper oxide–sulfide ore was studied. The identification tests showed that the sample is a mixture of quartz, chalcopyrite, galena, cerussite, hemimorphite and iron oxide minerals with 5.04% CuO, 1.61% PbO, 2.07% ZnO and 56.40% SiO2.
