经过十年的研究和在规模为24吨/日的中间工厂试验几个月后,瑞典MIMPRO公司宣布对镍离析的研究获得成功。离析用的氧化镍矿来自菲律宾,经煅烧后加入CaCl_2和焦炭进行离析。离析焙砂经磁选获得含Ni超过60%的精矿和90%以上的镍回收率。由于离析过程温度保持在950℃以下,故与160℃下进行熔炼的方法相比,工业生产的总能耗可节省25～30%。此法对于矿石的化学组成(尤其是碱度)有很大的适应性。该法采用新的发明—机械窑进行离析。
After a decade of research and months at a 24-tonne / day pilot plant in the Middle East, MIMPRO of Sweden announced a successful nickel segregation study. The nickel oxide ore for isolation is from the Philippines, calcined, and then added with CaCl 2 and coke for segregation. The calcined calcine obtained by magnetic separation more than 60% Ni concentrate and 90% nickel recovery. Since the temperature of the segregation is kept below 950 ° C, the total energy consumption of industrial production can be saved by 25 to 30% compared with the method of melting at 160 ° C. This method for the chemical composition of ores (especially alkalinity) have great adaptability. The law uses a new invention - mechanical kiln for segregation.
