FIELD: chemistry.
SUBSTANCE: device contains a conical reactor with a lid, a lower branch pipe of the input and an upper branch pipe of the output of a reaction mixture. It includes a unit of forced circulation consisting of a pump and connecting tubes. The unit of forced circulation includes internal and external contours. The internal contour is made in the form of a tube, which is placed vertically inside the reactor, with the tube facing a branch pipe of the input with the lower end, and in the upper part the tube is made in the form of an arch, placed in the horizontal plane and adjoining the internal wall of the reactor. The branch pipe of the input is equipped with a nozzle, which forms an ejection system with the lower end of an internal contour, and the branch pipe of the output of the reaction mixture is placed in the middle of the reactor lid and is made with a possibility of immersion into the reaction mixture.
EFFECT: intensification of leaching of metals and their compounds.
