Mineralogy Study on a Fine-Grained Cu-Mo Sulphide Ore in Jiudingshan China

This study researched mineralogy characteristics of Jiudingshan Cu-Mo sulphide ore by modern testing instruments, such as scanning electron microscope (SEM), reflected light microscope (RLM), X-ray diffractometer (XRD), and mineral liberation analyzer (MLA). The occurrence of Cu, Mo and other valuable minerals were mainly investigated. Results show that: it contain 0.50% Cu, 0.15% Mo and 7.04% Fe. Forty individual minerals are involved in the ore. Main valuable minerals are molybdenite, chalcopyrite, magnetite, pyrite; main gangue minerals are quartz, feldspar, garnet, calcite, dolomite.Molybdenite, chalcopyrite are finely disseminated in the magnetite,quartz, feldspar, garnet; some are inlayed along other minerals such as idocrase, actynolin.
