摘要:
以代表性镁质氧化镍矿为研究对象,就前期课题组提出的氧化镍矿非熔融金属化还原—磁选生产镍铁精矿技术开展了半工业试验和工业试验研究.半工业试验在内径?椎=0.45 m,长度L=7.5 m的回转窑中进行,而工业试验在内径?椎=3.2 m,长度L=72 m的回转窑中进行.技术主要分为原料准备、非熔融态金属化还原、水淬/球磨及磁选分离等4个工序.半工业试验连续运行50 d,共处理镍矿20 t,可获得镍、铁品位分别为7.4 %和69.6 %的镍铁精矿,且镍、铁回收率高达91.3 %和73.8 %,渣含镍则低至0.16 %.工业试验连续运行15 d,共处理镍矿8 000 t,取得了与半工业试验类似的结果,进一步验证了该新技术的可行性和稳定性.初步计算表明,吨镍铁精矿电耗约300 kWh,折合吨干基矿电耗约55 kWh.可见,文中提出的新技术能够实现镁质氧化镍矿在非熔融温度下充分金属化还原,达到富集镍和铁的目的.
