摘要
Abstract
In order to reduce the impurity of magnesium and manganese in Huangmailing phosphorite mine,improve the quality of phosphate concentrate.The test by direct flotation process,parameters of the flotation machine,and several inhibitors in acid and alkali conditions to remove magnesium manganese reduction test,from the speed of flotation machine,flotation aeration rate,inhibitors of NO-2 and dextrin dosage and pH adjustment agent (sodium carbonate and sodium hydroxide) amount of flotation.The raw ore grade ofP2O5 is 11.28％,MnO2 content of 1.70％,MgO content of 1.79％.The test results show that the final dressing index with P2O5 grade of 37.57％,recovery of 89.73％ by flow of one coarse one sweep one fine direct flotation in the pulp under the condition ofpH 11.8.The impurities contents of MnO2 and MgO in concentrates are reduced to 0.66％,0.36％.关键词
