摘要
通过化学分析、X衍射、光学显微镜等方法,对陕西某石墨型钼矿开展了矿物组成、粒度分析、赋矿岩性、矿物结构及构造、嵌布粒度等矿物学分析。结果表明:辉钼矿主要赋存在白云岩中,嵌布粒度微细,与黄铁矿、磁黄铁矿和石墨共生或伴生复杂,不利于选矿富集。
The sample pieces of graphite molybdenum in Shaanxi province were tested by means of chemical analysis,X-ray diffraction and optical microscope on mineral composition,grain size analysis,lithology for hosting ore,mineral structure and dissemination size.The analysis shows that the main molybdenite is invisible and is closely associated with pyrite,pyrrhotine and graphite exist in dolomite,the complex property is not good for flotation separation.
