Some tungsten resources have been found through the deep prospecting with the improved exploration technology. To determine the process flow and ore dressing indexes beneficiation tests were performed for rational development of resources. Based on the characteristics of the tungsten ore (mostly are silicate and carbonate), the combined technology of desulfurization, and normal temperature flotation process of scheelite in desulfurization tailings with sodium hydroxide as slurry pH regulator, sodium silicate as inhibitors of gangue minerals, 733 oxidized paraffinum sodium salt as collector was applied accompanied with favorable separating effects. Closed-circuit test index for the WO3 of tungsten concentrate grade was 62.29%, the recovery was 85.65%. It demonstrates the optional nature of the ore, which provides the technical basis for the future industrial production.
