The present application is used for gold mine slurry leaching operation, has large processing capacity, stable ore flow movement, uniform ore slurry mixing, large air flow, simple structure, and can effectively improve the leaching rate. However, the large-scale double-impeller leaching and stirring tank still has the following defects:

[0004] 1. In the prior art, only the existing device uses traditional single stirring shaft stirring, which has limited stirring range, making it easy for the ultra-large tank body to have stirring dead angles, making it difficult for the ore slurry to be uniformly mixed, and the material cannot be fully contacted with the leaching agent and the adsorbent. At the same time, the single-shaft stirring mode is difficult to adapt to different stages of ore slurry such as strong mixing in the early stage of leaching and gentle contact in the later stage of adsorption, resulting in low leaching and adsorption efficiency and high equipment operation and maintenance cost.

[0005] 2. In the prior art, the ore slurry often contains mineral particles of different hardness, which will continuously erode the surface of the paddle during stirring, causing the paddle to be easily worn, reducing the stirring efficiency, and making it difficult for the ore slurry to be fully and uniformly mixed, thereby affecting the leaching and adsorption effect and reducing the extraction rate of useful components.
