摘要
在实验室球磨试验的基础上,对天青石矿不同磨矿时间下的粒度分布进行了研究。对比了每个粒级所占的物料比率随时间的分布情况,并在此基础上建立了天青石矿的磨矿动力学方程,对磨矿过程进行了分析。运用X射线荧光光谱仪对不同磨矿时间下的锶质量分数进行了测定,为有用矿物的富集和矿泥的抛尾提供了依据。
On the basis of ball milling experiments in the laboratory,the particle size distribution of celestite was studied in different grinding time.The grinding kinetics equation was established on the basis of comparing the contribution of material ratio in each particle size fraction with time.The strontium content in different grinding time was measured by X-ray Fluorescence Spectrometry.It provided evidence for the concentration of valuable minerals and slime tailings discarding.
