| 摘 要： | 综述了我国铅锌矿中伴生贵金属金、银和稀散金属铟、锗和镓的资源概况，对相关回收技术进行了阐述。铅锌矿中的伴生金、银主要赋存于铅矿物中，低碱性条件有利于伴生金、银的浮选回收。稀散元素铟、锗和镓主要赋存于锌矿物中，回收率随锌矿物回收率的增加而增加；抑制锌的ZnSO4对稀散元素也有很强的抑制作用，CuSO4活化剂可显著提高稀散元素的品位及回收率。

| Abstract: | This paper summarizes the resources of gold, silver and indium, germanium and gallium in China''s lead-zinc mines, and expounds the related recovery technologies. The associated gold and silver in the lead-zinc ore mainly exist in the lead mineral. The low alkaline condition is favorable for the flotation recovery of the associated gold and silver. The rare elements indium, germanium and gallium mainly occur in zinc minerals, and the recovery rate increases with the increase of the recovery rate of zinc minerals; the ZnSO4 inhibiting zinc also has a strong inhibiting effect on the rare elements, and the CuSO4 activator can significantly improve the grade and recovery rate of the rare elements. |
