在对氰渣浮选时，采用合理的活化剂对铜的活化以及提高铜的回收率十分重要。
It is important to adopt a reasonable activator in order to activate copper and improve the copper recovery during cyanide residue flotation.
此法包括粉碎、筛选和浮选等过程。为了成功地实现铜的浮选，用黄药和黑药作捕收剂，硫化钠作活化剂。
The method consists of grinding, screening and flotation etc. in order to carry out flotation of copper successfully, xanthate and aerofloat are used as collectors and sodium sulfide as activator.
阴离子捕收剂反浮选时，铅盐和钙盐是浮选铝硅酸盐较理想的活化剂。
The lead salt and calcium salt are effective activators in the metal ions activation flotation by the anionic collectors.
