摘要:The beneficiation of diaspore with a low ratio of A/S can be realized by desilication using gradient flotation. The concentrate water can be reused in the flotation process after treating with BXF flocculant. Industrial tests of six months of continuous operation were conducted, and the results show that the concentrate with Al2O3 recovery of 83.04% is obtained, and the ratio of A/S increases from 4.46% in the raw ore to 9.57% in the concentrate. Moreover, the comprehensive reuse rate of the waste-water is 75%.
