Selective flotation of ilmenite from olivine using the

2016-12-10  As for olivine, the flotation recovery increases steadily from 19.35% to 70.31% as the collector concentration is increased from 1.0 × 10 − 4 M to 6.0 × 10 − 4 M. It is evident from the figure that the flotation recovery of both ilmenite and olivine are very high at a high concentrations of NaOL.

The effects of oxidation on the floation of chromite and olivine were studied in an effort to improve chromite recovery from domestic sources. The flotation behavior of pure chromite, pure olivine, and a chromite gravity concentrate were investigated. Freshly prepared chromite floated well between pH 2.2 and pH 4.5, but floated poorly at pH greater than 5.

2017-10-10  Fig. 2 presents the flotation recovery of ilmenite and olivine-pyroxene before and after acid surface dissolution as a function of pH values. In the case of ilmenite, two recovery peaks appear in the flotation recovery curve before and after acid surface dissolution. The appearance of these two peaks is in good agreement with the previous studies (Fan and Rowson, 2000a, Fan et al., 2009).
