Efficient matte and slag separation device and process for bottom blowing copper furnace

The invention relates to the technical field of nonferrous metallurgy, in particular to an efficient matte and slag separation device and process for a bottom blowing copper furnace. The device comprises a copper matte smelting furnace, a retaining wall, a slag baffle and a slagging plate; the bottom of the retaining wall is embedded in furnace lining bricks at the bottom of the copper matte smelting furnace and closely adhered to the furnace lining bricks, and an outer wall of the retaining wall is closely adhered to the wall of the copper matte smelting furnace, and copper holes and slag holes are formed in the retaining wall; the retaining wall divides the copper matte smelting furnace into two chambers, and a slagging plate is horizontally and fixedly connected in one of the chambers to divide the chamber into a slagging chamber and a copper matte tapping chamber; the bottom of the slag baffle is embedded in the copper matte tapping chamber; and the slagging chamber is provided with a slag outlet, and the
