KaoliniteKaolinite isRecovery anMicrobubble flotation essential non-metallic mineralMineral resource; its high purity products are widely used in chemical, electronics, construction and other industrial fields. KaoliniteKaolinite often coexists with vein mineralsMineral such as quartzQuartz, so it is important to separate and purify kaolin clayClays. According to the single-factor test, the problems of high collectorCollector consumption and low flotationFlotation yield exist in the conventional kaolin clayClays flotationFlotation process. In this paper, microbubble flotationMicrobubble flotation technology is used to improve the collision probability between bubbles and target mineralsMineral, so as to improve the flotationFlotation yield of kaolin clayClays. The results of the study showed that the flotationFlotation yield of kaolin clayClays reached more than 80% under the optimized process conditions. This study provides a new approach to enhancing the flotationFlotation process of fine-grained mineralsMineral.
