PROBLEM TO BE SOLVED: To provide a leaching vessel capable of improving the leaching rate of target metal.SOLUTION: This leaching vessel includes a cylindrical leaching vessel body 10, a stirrer 20 including a rotation axis 22 provided generally parallel to the central axis of the leaching vessel body 10 and a stirring blade 23 attached to the rotation axis 22, and a baffle 50 provided so as to cross the flow direction of a swirl flow generated by the stirrer 20. Since the baffle 50 makes an axial flow (a) to be the mainstream of the slurry flow in the leaching vessel 1, leading to uniform convection of the slurry, sufficient leaching reaction time can be ensured, and the leaching rate is improved. |
