摘要
为充分了解镜铁山矿区某铜矿工艺矿物学性质,并为制定合理的分选工艺提供基础资料,采用化学分析、X射线衍射、筛分分析、显微镜检测等分析手段,对镜铁山矿区某铜矿矿石的化学组成、矿物组成、矿物粒度特征和主要矿物的嵌布特征进行了详细研究。结果表明:该铜矿石矿物种类复杂,脉石成分较多,主要矿物嵌布关系复杂,嵌布粒度粗细不均。矿石中黄铜矿以中细粒嵌布为主,粒度不均匀,呈两极分化的特征,需结合选矿试验确定最佳的磨矿条件。研究结果对镜铁山矿区铜矿的合理开发利用具有一定指导意义。
In order to fully understand the process mineralogical properties of a copper mine in Jingtieshan mining area,and provide basic data for the development of reasonable separation technology. The chemical composition,mineral composition,mineral particle size characteristics and the distribution characteristics of main minerals of a copper ore in Jingtiesshan mining area were studied in detail through chemical analysis,X-ray diffraction,screening analysis and microscope examination. The results showed that the ore species of the copper deposit are complex,the gangue composition is more,the main mineral distribution relationship is complex,and the grain size of the dissemination is uneven. Chalcopyrite in the ore is mainly distributed in medium and fine grains,the particle size is not uniform,showing the characteristics of polarization.The best grinding conditions needs to be determined combined with the beneficiation test. This study has a certain guiding significance for the rational exploitation and utilization of copper ore in Jingtieshan mining area.
