The interaction of OM with sulphide minerals and its effects on their flotation are little understood. Although chalcopyrite recovery and grade are generally high in the flotation of most copper and molybdenum ores, this is not the case for molybdenite, whose flotation is much lower and sensitive to changes in hydrodynamic and pulp conditions in the flotation cell [9,10,11,12].

Introduction to Mineral Processing

The crushed copper ore (containing, for example, 0.75% Cu and 0.015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size. Lime and an oil for collecting molybdenum are usually added in the grinding circuit. A copper collector may also be added at this point. The pulp progresses to the flotation cells.
