北京矿冶研究院、北京钢铁研究院、承德钢铁厂、首都钢铁公司、东北工学院、北京有色研究院、长沙矿山没计院、重庆钢铁设计院、北京钢铁设计院等九个单位共同协作,从去年十月份开始至今年四月份止,在北京地区进行了钒钛磁铁精矿钠化法的全流程扩大性试验,并取得了初步成果。该新流程的重要特点在于铁精矿内的铁、钒、钛三元素都能获得高的回收率。“钠化球团”是该流程的第一道工序。其作用在于配有钠盐的球团在高温焙烧过程 Beijing Institute of Mining and Metallurgy, Beijing Iron and Steel Research Institute, Chengde Iron and Steel Plant, Capital Iron and Steel Company, Northeast Institute of Technology, Beijing Institute of Nonferrous Metals, Changsha Mining Institute, Chongqing Iron and Steel Design Institute, Beijing Iron and Steel Institute of Design and other nine units work together, From October last year until April this year, conducted in Beijing vanadium titanium magnetite concentrate the whole process of expansion test, and achieved initial results. An important feature of this new process is the high recovery of iron, vanadium and titanium in iron concentrates. The “sodium pellet” is the first process of the process. Its role is that with sodium salt pellets at high temperature roasting process
