摘　　要：天青石是制取各种锶化合物的主要原料。本文通过显微镜观察、扫描电镜能谱分析、化学多元素分析、摇床重选等手段,研究了云南兰坪县金顶白草坪天青石矿工艺矿物学特征和可选性。结果表明,矿石中天青石为锶元素赋存的目的矿物,呈板状,粒度为中-粗粒级,含锶高达50.24%。采用摇床重选工艺和-0.2mm的入选细度可有效富集天青石。Celestite is the important raw material in production of various Sr compound.In this paper,we have studied Jinding Baicaoping celestite technological mineralogical characteritics and washability with microscope,scanning electron microscope energy spectrum analysis,chemical analysis and shaking table,etc in Lanping,Yunnan,showing the celestite in ore is Sr-bearing objective mineral,board-form,medium-coarse grained,high Sr content 50.24%.The celestite can be concentrated effectively wth shaking table by gravity concentration and chosen grained 0.2mm.
