福建砷菱铅矾的工艺矿物学研究

Study on Process Mineralogy of Beudantite Mineral of a Limonite Ore in Fujian

通过镜下鉴定、X衍射分析、电子探针分析、热分析和物理性质测定等多种手段对福建某褐铁矿矿石中一种含铅砷酸盐类矿物的光学性质、化学成分和产出形式等特征进行了较详细的研究,最终查明该矿物为砷菱铅矾。同时根据砷菱铅矾与褐铁矿的嵌布关系对矿石的可选性进行了评价。

By means of microscopic analysis,X-ray diffraction,electron probe microanalysis,thermal analysis and physical property analysis,the optical features,chemical component and occurrence of the Pb-bearing arsenate mineral in a limonite ore of Fujian were investigated thoroughly,and ultimately,it was found out that this mineral is beudantite.According to the intergrowth relations between beudantite and limonite,the beneficiability of this limonite ore was evaluated.
