Device for leaching valuable metals in copper-nickel tailings

Abstract

The invention belongs to the technical field of precious metal preparation, and particularly relates to a leaching device for valuable metal in copper-nickel tailings, which comprises a base, a leaching box is fixedly connected to the top end of the base, a bearing frame is inserted into the leaching box, a plurality of filter screens are fixedly connected into the bearing frame, and a plurality of discharge ports are formed in the side surface of the bearing frame; according to the leaching device for the valuable metal in the copper-nickel tailings, the filter screen is arranged, the tailings are placed on the filter screen in the using process, then when the tailings make contact with a leaching agent, precious metal in the tailings can be gradually fused into the leaching agent, the size of the blocky tailings is gradually reduced, and the leaching effect is better. Impurity particles attached to the tailings can fall off from the tailings and then are received by the filter screen, and then the filter screen is driven to be separated from the leaching box, so that the impurity particles are separated from the leaching liquid, waiting for impurity precipitation is not needed, and the overall leaching efficiency of the precious metal in the tailings is improved.
