Description
The effect of various dispersion parameters; such as slurry pH, solid concentration, stirring speed and time, and water quality has been extensively studied for stabilization the ultra fine iron ore slurry prior to selective flocculation. The PZC of Dilband iron ore system was found by using the Zetaphormeter III (CAD E 400) at pH value of 4.25. The set of dispersion parameters was optimized on the basis of weight percent and the percent entrapment of fine particles (10 mu m) sedimented in 2.5 min settling time. Finally the selectivity of the optimal dispersion parameters was evaluated on the basis of elemental analysis of the sediment. The optimal conditions for 38 mum ultra fine iron ore slurry in double distilled water were found at concentration of 7.5% solid, pH 10.5, stirring speed 2000 rpm, and stirring time 5 min. (author)
