某高镁难选低品位胶磷矿浮选工艺研究

摘要

In view of the characteristics of some low grade collophanite with high content of magnesium, based on studying on the mineral chemical composition of raw ore, series of experiments were tested and the optimum process parameters were determined. A phosphate concentrate with a grade of 30.33% P2O5 and a recovery of 76.57% was obtained by reverse lfotation lfowsheet.%针对某高镁难选低品位胶磷矿的矿物学特点，在查明试样多元素分析和目的矿物成分的基础上，进行了大量条件试验，确定了最佳的工艺参数，采用反浮选工艺流程，针对含P2O517.60%的原矿，最终可获得磷精矿P2O5品位30.33%，回收率76.57%的指标。
