[0002] During the treatment of cyanide slag, it is necessary to add a decyanide agent, and then use a pretreatment agent to pretreat the tailings after decyanide treatment, and finally use a cyanide-free agent to etch gold. There is a filtrate circulation treatment process in the existing cyanide slag treatment process, the purpose of which is to ensure that the cyanide slag is treated cleanly and thoroughly. However, in addition to the insufficient amount of agent added, another reason for the incomplete treatment of cyanide slag is that the cyanide slag will clump, that is, part of the cyanide slag will form a mass, and the inside cannot be exposed to the agent, which leads to incomplete treatment. Therefore, filtrate circulation treatment is required. However, in actual situations, the filtrate circulation treatment time is relatively long, and it is necessary to continue to add agents to it. The total amount of drugs used is large, and one circulation treatment may not necessarily clean all the agglomerated cyanide slag. In order to ensure thorough cleaning, it is often necessary to circulate 2-3 times, and the cleaning time is relatively long. Utility Model Content
