Research on Cationic Reverse Flotation of Magnetic Concentrate Using a Flotation Column

An experimental research to improve the grade of a magnetic concentrate from a concentrator using the cationic reverse floatation technology in the countercurrent bubble contact flotation column was conducted. The conditional tests of the pharmaceutical system and the flotation column operating parameters were done. The results show that the iron concentrate with the grade of 70.06% and iron recovery of 93.18% can be achieved according to the flow sheet o f one roughing and two scavengings under the optimal conditions. And the tailing grade is 12.08%.
