Embodiment 1
[0031] Such as Figure 1-2 shown.
[0032] An inflatable stirring cyanidation leaching gold extraction tank, comprising a carbon steel tank body 9, a carbon steel tank cover 11, a heating pipe 7 and seven pulp guide tubes 8; the pulp guide tubes 8 are vertically arranged on the carbon steel tank body 9; the slurry guide tube 8 is provided with an inflatable stirring tube 17; the heating tube 7 is arranged around the side wall of the carbon steel tank 9. When the aeration and agitation cyanidation leaching gold extraction tank of the present invention is in use, compressed air is input into the aeration agitation tube 17 through a compressor to perform agitation while aerating. Arranging the inflatable stirring tube 17 in the pulp guide tube 8 avoids the direct contact of the inflatable stirring tube 17 with the pulp, preventing the ore pulp from entering the inflatable stirring tube 17 and causing plugging. Another advantage of this structure is that the pressure air output ...
Embodiment 2
[0034] The gas-inflated stirring cyanidation leaching gold extraction tank as described in Example 1 is different in that the carbon steel tank body 9 is a cylindrical carbon steel tank body with a height-to-diameter ratio of 2; the slurry guide tube 8 is made of carbon steel , the diameter is 500mm; the diameter of the inflatable stirring tube 17 is 30mm; the distance between the slurry guide tube 8 and the bottom of the carbon steel tank 9 is 1000mm. Within this distance range, the mixing effect of the pulp is the best and the dispersion of the pulp is better.
Embodiment 3
[0036] The gas-inflated stirring cyanidation leaching gold extraction tank as described in Example 1 is different in that the heating pipe 7 has a diameter of 50 mm, and a third flow regulating valve 18 is provided at the inlet of the heating pipe 7 . The flow regulating valve is used to control the flow of hot water entering the HVAC pipe 7, and the HVAC pipe 7 heats the ore pulp in cold winter weather to stabilize the reaction temperature.
