摘要
目的:研究青黛泡沫浮选机理,为青黛泡沫浮选工业化提供应用基础理论支持。方法:对粗靛泡沫浮选中的关键问题:粗靛浮选前后粒子粒度分布的改变、粗靛中存在的起泡物质的表面活性、泡沫对靛粒子和非靛粒子(CaCO3)的吸附性差异、靛粒子对不同表面活性剂吸附能力差异等进行研究。结果:靛粒子易被泡沫吸附,非靛粒子(CaCO3)则不被吸附。粗靛体系中存在在碱性条件下具有较好起泡性的物质。在碱性条件下,靛粒子能与强酸性表面活性剂的泡沫产生吸附作用。结论:应用粗靛体系自身表面活性物质,在碱性条件下,采用泡沫浮选法能有效的对粗靛进行精制。
AIM ： To study the mechanism of foam floatation in the processing of Indigo Raturalis, and provide theory to support the industrialization of Indigo Raturalis processing by foam fioatation technique. METHODS： To study the critical problems of the processing of Indigo Raturalis by foam floatation technique ： the change of particle size distribution after the processing of Indigo Raturalis ; The surface activity of frothing materials in Indigo Raturalis; the distinction of the foam to absorb the Indigo particles and other particles （ CaCO3 ） ; the absorbability of the Indigo particles to absorb different surface active agents. RESULTS： 1. The Indigo particles were easily absorbed by the foam, but others （CaCO3 ） were not; 2. There were some frothing materials with good frothing capability in the alkaline system of Indigo Raturalis,3 In the alkaline system, the Indigo particles could be absorbed by the foam of strong acid surface active agents. CONCLUSION ： In the alkaline system of Indigo Raturalis, with itself surface active agents, it is effective to process Indigo Raturalis by foam floatation technique.
