Fig. 1, Fig. 2 show flotation results obtained with two different chalcopyritic Cu–Mo ore samples floated in fresh water and sea water. Molybdenite flotation in sea water was depressed in alkaline solutions when pH was higher than 9.0–9.5. At the same time, Cu recovery was only slightly reduced and was not significantly affected by pH.

construction and design is also simpler. The basic difference between column flotation and mechanical flotation is that column flotation does not have an agitator. Air bubbles in the column flotation are generated from the air flow through the sparger (1). Meanwhile, the mechanical flotation cell mechanism uses an agitator to produce air bubbles.
