ABSTRACT
APR (air to pulp ratio) and bias factor are important operating parameters in the flotation of Jameson Cell. These parameters have significant effects on the micro-events between particles and bubbles in flotation, and hence in flotation performance. In this study, the possibilities of obtaining a Cu-Zn rich bulk concentrate from Cayeli region which have complex sulphide Cu-Zn ores having problematic flotation behaviour resulting from very fine liberation size and oxidation were investigated by using the Jameson Cell, and the effects of APR and bias factor on flotation recovery have been carried out. According to the results, it has been observed that complex sulphide Cu-Zn ores can be successfully enriched in single stage from the grade and recovery point of view. It has been determined that APR and bias factor have a significant effect on flotation recovery. In the flotation of rather fine particle minerals, the optimum values of APR and bias factor have been established as needed to be within the range of, 1-1.5 and 0.70-0.95, respectively.
