Abstract The characteristics of mineral floatability, namely, the wetting angle and the induction time, are examined. The agreement between the predicted floatability using these characteristics and the theoretical and experimental data is accessed. It is found that hydrophobicity defined by the wetting angle is not always a quantitative …
Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review
In addition to the froth flotation technique, another technique used to recover chalcopyrite is electroflotation. The basis of this technique is the production of small bubbles (0.008–0.015 mm) through the application of electric current. Electrodes are placed in the mineral pulp, thus causing electrolysis of the water.
CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION …
Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1. In practice the most ...
