Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the drawings and embodiments:
[0017] As Figure 1-2 shown, it includes a primary stirring barrel 1 and a secondary stirring barrel 2. The upper part of the secondary stirring barrel 2 is connected to the primary stirring barrel 1, and a valve is provided between the primary stirring barrel 1 and the secondary stirring barrel 2; a sintering machine head ash inlet 11 and a clear water inlet 12 are provided at the top of the primary stirring barrel 1, a clear liquid outlet 21 is provided on one side of the upper end of the secondary stirring barrel 2, an environmental protection gold extraction agent inlet 22 is provided on the other side of the upper end of the secondary stirring barrel 2, and a mortar outlet 23 is provided at the bottom of the secondary stirring barrel 2.
[0018] The sintering machine head ash inlet 11 is used to add sintering machine head ash, and the clean water inlet 12 is used to add clean water. After adding the sintering machine head ash and clean water, the two are subjected to primary stirring in the first stirring tank to form a slurry. After the stirring is completed, the valve is opened, and the slurry falls into the second stirring tank.
[0019] The slurry in the second stirring tank is first allowed to stand and precipitate, and the supernatant liquid on the upper layer is discharged outwards through the supernatant liquid outlet. After the determination of the supernatant liquid, the silver content therein is 360 - 400 g / t, and the gold content is 95 - 105 g / t;
[0020] Then, the slurry in the second stirring tank is subjected to secondary stirring to adjust the pH value; then, an environmentally friendly gold extraction agent is added to the environmentally friendly gold extraction agent inlet 22, and stirring and standing are carried out again; after the standing is completed, the slurry is discharged through the slurry outlet 23 and dehydrated and dried. After detection, the silver extraction rate reaches 92.76%, and the gold extraction rate reaches 94.33%.
[0021] The utility model adopts a first - stage stirring tank 1 and a second - stage stirring tank 2 for two - stage stirring, which can maximize the extraction of heavy metal ions in the slurry and improve the recovery rate of heavy metal ions.

[0024] Furthermore, a guiding hopper 9 is arranged at the top of the connecting pipe 3, and the top of the guiding hopper 9 is connected to the first - stage stirring tank 1. Specifically, the guiding hopper 9 is in a funnel shape. It ensures that the slurry can flow smoothly and accurately into the second - stage stirring tank 2, avoiding waste and pollution.
[0025] Furthermore, legs 10 are arranged at the bottom of the second - stage stirring tank 2 to support the entire slurry - adjusting device, making the entire production process more stable.
