Abstract

Guizhou has a rich bauxite resources, including a part reserves of poor bauxite. Based on a series of the past positive flotation and reverse flotation condition test, we found the reverse flotations are better to improve aluminasilica ratio. In this study, we collected the fresh ore samples in several mining areas in Central Guizhou. And bauxite sintering dissolution tests show that A12O3 dissolution rate is high after the bauxite ingredients sintering, 1# sample and 2# sample dissolution rates are much higher than the flotation recoveries, and because aluminum silicon ratio of 2# sample is a little higher, the dissolution rate can reach 75.64%. The test results show that positive flotation is not fit for poor bauxite, reverse flotation process can obtain a certain effect, and the sintering aluminum process can fully recycle the useful minerals.
