Cyanide Leaching Agitation Tank for Gold CIL Plant - Made-in-China

The pulp diffuses along the radial direction at the bottom of the tank then flows upward along the circular wall of the tank, thus a closed cycle is formed. If the machine is used as a leaching tank, the leaching agent solution and air are filled into the tank, and the leaching agent and air are evenly distributed in the tank to leach gold.
