中文摘要：我国四川省攀西地区钒钛磁铁矿资源中钛资源储量巨大,主要以钛精矿形式回收利用,并主要用于硫酸法钛白和酸溶性钛渣生产原料,其产量占全国钛原料市场的75％以上.硫酸法钛白工艺技术成熟,已形成相对完整的"内循环",但尚未全面突破硫酸法钛白联产技术;电炉冶炼酸溶性钛渣工艺技术较成熟,主流工艺是钛精矿不预处理-实心圆形电极-密闭圆形电炉连续冶炼工艺,钛精矿酸性氧化球团-电炉冶炼一步法工艺、大功率矩圆形电炉冶炼酸溶性钛渣等钛渣新工艺发展较快、发展空间大,是今后主要发展方向.目前攀西地区发展钛产业的一个主要问题是缺乏沸腾氯化法钛白工艺需求的高品位钛资源,未来需要突破攀西高钙镁钛精矿除杂提质制取高品位高钛渣关键核心技术,并同时研发攻关硫酸法钛白附产绿矾和钛石膏回收循环利用技术、高炉钛渣提钛及综合利用技术、钒钛铁精矿非高炉炼铁新技术,以及以钛精矿、钛渣或钛白粉为原料制备含钛及钛基新材料技术,以期获得攀西钛产业的健康可持续发展.

外文摘要：There are huge reserves of titanium resources in vanadium-titanium magnetite in Panxi area of Sichuan Province,China,which are mainly recycled in the form of titanium concentrate and mainly used as raw materials for the production of titanium dioxide and acid-soluble titanium slag by sulfuric acid method.Its output accounts for more than 75％of the national titanium raw material market.The process technology of titanium dioxide by sulfuric acid method is mature,but the co-production technology of titanium dioxide by sulfuric acid method has not been fully broken through.The technology of smelting acid-soluble titanium slag by electric furnace is relatively mature,and the main process is the continuous smelting process of titanium concentrate without pretreatment-solid circular electrode-closed circular electric furnace.The new process of titanium slag such as titanium concentrate acid oxidation pellet-electric furnace smelting one-step process and high-power rectangular circular electric furnace smelting acid-soluble titanium slag has developed rapidly and has a large development space,which is the main development direction in the future.At present,one of the main problems in the development of titanium industry in Panxi area is the lack of high-grade titanium resources required by the boiling chlorination titanium dioxide process.In the future,it is necessary to break through the key technology of removing impurities and improving the quality of Panxi high-calcium magnesium ilmenite concentrate to produce high-grade high-titanium slag.At the same time,the recovery and recycling technologies of green vitriol and titanium gypsum,the technology of titanium extraction and comprehensive utilization of blast furnace titanium slag,the new technology of non-blast furnace ironmaking of vanadium-titanium iron concentrate,and the technology of preparing titanium-containing and titanium-based new materials with titanium concentrate,titanium slag or titanium dioxide as raw materials shouldbe studied and developed,in order to obtain the healthy and sustainable development of Panxi titanium industry.
