黄金冶炼废水回收及回用处理技术实践

摘要

黄金冶炼废水主要由酸性废水和含氰废水组成，按照废水“回收+回用处理”的处理原则，采用3项专利技术，废水处理回收了氰化钠和硫氰化亚铜，实现了废水100%回用。%Waste water of gold smelting mainly consists of acid waste water and cyanide-containing waste. In accordance with the principle of " recycling and reuse treatment" for waste water, three patent technologies are adopted. The waste water treatment recovers sodium cyanide and cuprous rhodanide, achieving the goal that waste water is 100% reused.
