摘要
以硝酸为氧化剂、硫酸为添加剂的混酸体系用于铜镍硫化矿尾矿中镍、铜、钴等有价金属的浸出,镍、铜、钴浸出率分别可达91.5%,85.0%和54.6%。放大试验表明,这一混酸浸出方法的效果良好、操作简便稳定。
A mixed nitric-sulphuric acids is used to recover the valuable metals Ni, Cu and Co from low-grade Ni- Cu sulfide railings, the leaching rate of Ni, Cu, and Co is 91.5 %, 85.0 % and 54.6 % respectively under laboratory conditions. This leaching procedure is operationally simple and economical, which may be applicable in an industry scale for the recovery of valuable metals from Ni-Cu sulfide tailings.
