摘要
以黄原酸盐类和二乙基二硫代氨基甲酸钠为捕收剂,在冶炼废水中进行了镍钴离子浮选试验,查明了捕收剂用量、pH 值、电解质等对浮选的影响,指出用离子浮选法可以成功处理镍钴冶炼废水。在捕收剂按镍钴化学式量添加,浮选 pH6—10的条件下,可以得到含镍钴分别低于3毫克/升的处理水。废水中大量碳酸盐的存在对镍浮选影响不大,对钴浮选有害,使钴回收率降低。浮选试验结果与已报道的理论计算预测完全一致。
Ion flotation of nickel and cobalt in refinery's waste water was car-ried out using xanthates and diethyl-dithiocarbamate as a collector,and the effects of collector addition,pH and other electrolytes on theflotation recovery were examined.It was shown that ion flotation wasa effective method for the treatment of the waste water of nickel andcobalt.When the stoichiometric collector for nickel and cobalt wasadded in waste water of pH 6～10,water containing lower than 3ppmof nickel or cobalt could be obtained ...
