摘要
通过对贵州织金新华磷矿磨矿细度的实验研究,分析了磨矿时间对磨矿细度的影响。实验结果表明:磨矿时间短,磨矿细度小,随着磨矿时间的延长,磨矿细度增加;根据浮选实验确定,磨矿的最佳时间为7min,磨矿细度为87.35%;磨好的矿样经充分混合取样分析表明,矿样P_2O_5含量为21.90%,MgO的含量为6.42%,稀土含量为0.0861%。
This paper based on the experimental studies of phosphorus rock＇s grinding fineness in XingHua,ZiJing GuiZhou. Mainly study of the grinding time＇ s effect on grinding fineness. The result shows： the shorter the grinding time, the smaller the grinding fineness, as the grinding time extended, the grinding fineness increased. As the Flotation Experiments confirmed. The best grinding time is 7 mins, the grinding fineness is 87.35% ; Good grinding ore samples by the well - mixed sample analysis shows that the P2O5 of the mineral aample takes 21.90%. MgO takes 6.42% and the Rare Earth Element takes 0.0861%.
