摘要
Based on microscopic observation of polished section and slice, phase analysis, electronic probing and X-ray powdered crystal diffraction, it is suggested that the primary beneficial element is tungsten and secondary molybdenum in the ores from the Gaojiabang tungsten-molybdenum deposit, Qingyang County, Anhui Province, other elements are insufficient for comprehensive use, and harmful components may be removed after processing. Major tungsten-bearing ore is scheelite and molybdenum 2 H1 molybdenite. Mineralizing temperature ranges from 700 to 900 ℃. The substantial ore in natural state is hosted in skarn and breccia. Scheelite exists as euhedral and subhedral, with grain size being 0.1~0.5 mm, and molybdenite euhedral sheetlike ranging 0.1~0.15 mm. The ores occur structurally more as disseminated, less stringer disseminated, and ore gap filling dominates.
