Jan 01, 2019  From this study the recovery of MnO 2 by using froth flotation technique was (85.41%) achieved. The optimum time of flotation obtained for manganese is 9 minutes. At 9 minutes, the optimum variables obtained are collector dosage of 2.5 gm/ml of feed and frother 2 gm/ml, depressant 1.5 gm/ml and pH is 8. The frother dosage has shown marginal ...
