Wang Y.H. [48] trialed a process for antimony oxide ore involving re-flotation and separation. It involves selectively disintegrating quartz-calcite type antimony oxide ore (with Sb content of 0.50– 7.50%), and pre-enriching the antimony oxide using a re-selection method to obtain a rough concentrate. With pH adjusted to 9–11, a C10-18 ...
