[0043] In this embodiment, the mud rich in precious metals is injected into the leaching tank 1 and mixed with a flocculant. Under the action of the flocculant, the solid particles in the mud sink, and a clarified liquid appears in the upper layer. The clarified liquid is enriched with precious metal elements, and the flocculants are precipitated to the lower layer. Injecting different types of mud components or different mud injection amounts into the leaching tank 1 may cause different heights of the solid-liquid interface after the mud solid-liquid stratification, which will cause the clarified liquid layer to be located at different positions. In order to discharge the clarified liquid at different heights of the solid-liquid interface, a plurality of outlets 101 arranged vertically in sequence are provided on the side of the leaching tank 1, and each outlet 101 is connected to a liquid outlet branch pipe 2, and the liquid outlet branch pipes 2 converge into the liquid outlet collection pipe 4. Each liquid outlet branch pipe 2 is provided with a first liquid outlet valve 3. According to the height of the solid-liquid separation surface, different numbers of first liquid outlet valves 3 with suitable heights can be opened, and the clarified liquid flows out from the outlet 101 and finally collects in the liquid outlet collecting pipe 4. Finally, it is well achieved that no matter where the lower end of the clarified liquid layer is located, the clarified liquid layer can be discharged through one or several corresponding first liquid outlet valves 3. Compared with the clarified liquid discharge method in the prior art, not only is the clarified liquid discharge efficiency high, but also the applicability is wide.
