一、绪言近年来,随着镍需要量的增长和由于处理镍矿石的品位愈来愈低,因此含镍红土矿的利用,引起很大的注意。过去对于含镍红土矿的处理方法有氯化法,硫酸化法,离析法,氨法,羰基法。到目前为止,日本还没有走上工业化,原因是这些 I. INTRODUCTION In recent years, the use of nickel-bearing laterites has drawn much attention as the demand for nickel increases and the grade of nickel ore processed becomes lower and lower. In the past for the nickel-containing laterite processing methods are chlorination, sulfation, separation, ammonia, carbonyl method. So far, Japan has not embarked on industrialization for these reasons
