摘　　要：采用旋流-静态微泡浮选柱对某胶磷矿进行了半工业试验研究,在原矿品位为23.73%P2O5的情况下通过正-反浮选流程获得了精矿P2O5品位29.78%、MgO品位0.29%,回收率82.69%的良好指标,缩短了流程结构.为浮选柱技术的工业应用进行了积极探索.This study makes a semi-industrial experimental investigation on the phosphate rock by using cyclonic-static micro-bubble flotation column.With the application of direct-reverse flotation process flow,it carries out a good indicator with content of P2O5 concentrate 29.78%,content of MgO 0.29%,recovery rate 82.69% when raw mine grade is 23.73%.It shortens the process structure and makes an active exploration on the industrial application of flotation column technology.
