Influencing factors and control measures of phosphorus content in phosphorus tailings
To reduce the P2O5 content in phosphate ore flotation tailings,a large amount of production data is analyzed,and various processes are compared to identify the factors affecting the phosphorus content in the phosphorus tailings.These factors mainly include unreasonable height adjustment of the overflow plate,untimely pH adjustment,excessive opening of the inflation valve,insufficient frequency of inhibitor acidity detection,and inappropriate ratio of phosphorus and magnesium content in the raw ore;And quick win improvement and factor improvement measures for each influencing factor are carried out.The implementation of various control measures has achieved the goal of reducing the phosphorus content in tailings,which has decreased from 2.94%to 2.75%.
