摘要:
通过磷矿颗粒的分级浮选、药剂对比及组合浮选对湖北保康钙质磷矿和大峪口硅钙质磷矿进行了系统研究.结果表明：分级后粒径为-65 μm的小颗粒磷矿更有利于反浮选，且保康磷矿反浮选效果优于大峪口磷矿；复合药剂和酸性抑制剂均能改善保康钙质磷矿浮选效果，最终磷精矿品位达到36.14%，磷回收率为96.10%；药剂表面张力降低能增强药剂对磷矿颗粒的湿润.最后，通过测量电动电位和亲水亲油平衡值，对浮选过程效率进行了分析，并对浮选机理进行了讨论.
Abstract:
A systematic investigations about Hubei Baokang calcium phosphate ore and Dayukou silicon calcium phosphate ore were made by grade flotation,reagent contrast and combination flotation analysis.The results show that the small phosphate ore particles of 65 μm after grading are beneficial to reverse flotation,and the reverse flotation effect of Baokang phosphate ore is better than that of Dayukou;both complex reagent and acid inhibitor can improve the flotation effect of Baokang calcium phosphate ore;finally,the grade of phosphate concentrate reaches 36.14%,and the recovery rate of phosphate is 96.10%;the decrease of reagent surface tension can enhance the reagent wettability of phosphate ore particle.We also analyzed the flotation process efficiency and discussed the flotation mechanism through measuring zeta potential and hydrophile lipophile balance number.
