  • Experimental Studies on Column Flotation Cell

    An experimental column flotation cell was designed and fabricated in the laboratory and experiments were carried out by varying the operational parameters. Based on the experiments the optimum values of these parameters were found to be 0.15 m3/hr of water flow rate

    All the experimental data validate the hypothesis that kaolinite covers molybdenite reducing its flotation recovery. The depressing effect of kaolinite on molybdenite flotation in seawater is enhanced by the magnesium and calcium hydroxo complexes at pH > 9 which induce heterocoagulation between kaolinite and molybdenite thus reducing recovery.

  • Discrimination of Six Flotation Kinetic Models Used in the

    In this study experimental results of conventional flotation and carrier flotation were characterized by six commonly used flotation kinetic models. Two statistical criteria (coefficient of determination R2 and root mean square error RMSE) were used for comparison of fitting performance of different models. All kinetic models tested gave good levels of goodness of fit but the second-order
