Reverse flotation studies on an Indian low-grade iron ore slimes

Vijaya Kumar, T V and Rao, D S and Subba Rao, S and Prabhakar, S and Bhaskar Raju, G (2010) Reverse flotation studies on an Indian low-grade iron ore slimes. International Journal of Engineering Science and Technology, 2 (4). pp. 637-648.



The present investigation deals with the recovery of iron values from the screw classifier overflow slimes from an iron ore washing plant by means of reverse cationic flotation as an alternate to direct anionic flotation. Selectivity index, an indicator of separation efficiency, was chosen as the response parameter for optimizing the quantity and evaluating a series of generically same but chemically different cationic collectors used in reverse flotation and for further optimization of other flotation process parameters. In the optimization, the main variables investigated were percent solids, collector and depressant dosage. An increase in the iron content of the concentrates is obtained with concomitant reduction in Si02 and Al203levels.
