摘　　要：以云南红舍克堆积型铝土矿为研究对象开展工艺矿物学研究工作。运用多元素分析、X-射线衍射分析、扫描电镜和MLA等手段,研究该堆积型铝土矿的化学组成、主要矿物组成、粒度组成、嵌布特征及矿物单体解离等工艺性质。结果表明,原矿中主要目的矿物为一水软铝石、硬水铝石、三水铝石,主要脉石矿物为高岭石,其他金属矿物为赤(褐)铁矿和锐钛矿。该研究可作为此铝土矿合理开发利用的理论基础。Targeted at accumulative bauxite in Hongsheke, Yunnan province, we carried out process mineralo-gy research work. Through multi-element analysis, XRD,SEM,MLA and other measurements, the detailed process mineralogical studies on the accumulative bauxite were carried out to identify the chemical composition, mineral composition, grain size distribution, dissemination and liberation characteristics of the ore. The results showed that the main objective minerals are boehmite, diaspore and gibbsite, the main gangue mineral is kaolinite, and the other metallic minerals are hematite, limonite and anatase. The results can provide the theoretical basic for reasonable exploitation of the bauxite.
