Effect of Pb2+ ions on ilmenite flotation and adsorption

Dec 15, 2017The flotation recoveries of ilmenite in the presence and absence of Pb 2+ ions using BHA as a collector as a function of pH are shown in Fig. 2.Without the addition of Pb 2+ ions, the flotation recovery of ilmenite is only 6.05% at pH 4.5. Generally, the recovery rate increases with pH, reaching a maximum of about 45% at pH 5.5.

The flotation reagents can be added in a feed-forward fashion based on the plant raw coal tonnage. Automatic feedback control of the flotation reagent addition rates has been lacking due to the unavailability of sensors for determining the quality of the froth cell tailings. Expensive nuclear-based sensors have been tried with limited success.
