摘要
用溶剂萃取法代替目前广泛使用的金泥处理方法，可以节约资源，降低成本，提高金的回收率，还能回收金泥中的银，产品金的纯度在９９．９％以上；连续作业，操作方便，大大减轻劳动强度和改善工作条件，而且便于自动化操作管理，是一种社会、环境、经济三种效益都挂的成熟技术，应大力推广应用。
Employing the method of solvent extraction to replace the widespreadly and presently used method of treating gold slime, the gold recovery can be improved, natural resources cut down and capital cost reduced. Furthermore, the silver in gold slime also can be recovered and the purity of finished gold is able to reach to 99.9% or more. In addition, this method is not only easy to be operated continuously With greatly reduced labor intensity and improved working conditions but convenient to be managed automatieally. Insllo rt, this technique whose economic environmental and social benefit are all fine should be popularized energetically
