Title: Process Mineralogy of a Skarn Tungsten-Molybdenum Ore
Abstract: The researches on a skarn tungsten-molybdenum ore by the internationally advanced MLA testing technology and traditional process mineralogy show that the grade of W and Mo is low with high comprehensive recycling value. The tungsten mainly occurs in the form of scheelite while the molybdenum principally exists as molybdenite, and the molybdenum as isomorphous addition existing in the lattice of scheelite accounts for 16.89 % of the total molybdenum. The liberation degree of scheelite is close to 90 % while that of molybdenite is less than 80% at the grinding fineness 62 %-0.074 mm. The tungsten and molybdenum contained in the magnetic gangue minerals accounts for 2.8 % and 5.8 % respectively. Considering that the magnetic gangue minerals including andradite tremolite, diopside, etc account for about two-thirds of the total and are not closely intergrown with scheelite or molybdenite, pre-discarding these magnetic gangue minerals by high intensity magnetic separation is available so as to simplify the cleaning process of tungsten as well as molybdenum.
