Study on New Highly Effective Technique of Dressing-smelting for Complex Refractory Tantalum Niobium Tungsten Ore
A new technique has been developed for comprehensively recovering tantalum niobium tungsten ore by adoption of stage grinding, stage separation, combination of flotation and gravity separation,gravity separation for coarse particles, flotation for fine ones, combination of ore-dressing and hydrometallurgy. The new type and high efficiency combinative collector mainly composed of benzyl hydroxamic acid is firstly used to treat tantalum niobium and tungsten slime, besides the new type equipment for gravitational separation -YTF-C shaking table for fine particles is adopted to treat flotation rough concentrate, hence having notably enhanced both recovery and concentrate grade of fine tantalum niobium and tungsten minerals. The commercial test obtains the tantalum concentrate assaying Ta2O5 31.98% with recovery 43.44% and tungsten product assaying WO3 89.40% with recovery 76.02%. The developed technique provides a reliable approach and an effective way for comprehensive utilization of lean fine complex refractory tantalum niobium tungsten ore resource.
