    • The separation method for zinc sulfide, in the hydrometallurgical process by a High Pressure Acid Leach for nickel oxide ore comprising leaching and solid/liquid separation step, neutralization step, zinc removal step, and nickel recovery step, which can inhibit clogging of a filter cloth and reduce a frequency of washing operation and replacement operation of a filter cloth by improving filtration performance of zinc sulfide, and inhibit decrease of nickel recovery ratio, in the zinc removal step in which zinc sulfide is formed by adding a sulfurizing agent to the neutralization final liquid containing zinc as well as nickel and cobalt and zinc sulfide is separated to obtain a mother liquid for nickel recovery containing nickel and cobalt.The separation method for zinc sulfide of the present invention is characterized in that in the above-described neutralization step, the leach residue is added to the leach liquor, and pH of the neutralization final liquid is adjusted so as to fall to the range from 3.0 to 3.5, and in the zinc removal step, the suspended solid comprising the neutralized precipitate and the leaching reside are kept remained in said neutralization final liquid so that turbidity thereof falls in the range from 100 to 400 NTU.
    • 硫化锌的分离方法,在通过高压酸浸法进行的氧化镍矿石的湿法冶金工艺中,包括浸出和固/液分离步骤,中和步骤,锌除去步骤和镍回收步骤,其可以抑制滤布堵塞 通过提高硫化锌的过滤性能来降低洗涤操作和更换操作的频率,并且通过在中和最终添加硫化剂的锌硫化物的除锌步骤中抑制镍回收率的降低 分离含有锌以及镍和钴和硫化锌的液体,以获得含镍和钴的镍回收母液。 本发明的硫化锌的分离方法的特征在于,在上述中和工序中,将浸出残渣加入到浸出液中,调节中和最终液体的pH,使其降至3.0 至3.5,并且在锌去除步骤中,将包含中和的沉淀物和浸出的悬浮固体保持在所述中和最终液体中,使得其浊度在100至400NTU的范围内。
