The invention provides a continuous copper removal method for crude lead. The method includes the steps that crude lead liquid is introduced into a copper removal furnace to form a molten pool, the temperature of the molten pool is controlled to be gradually lowered from top to bottom, the temperature of the top of the molten pool is 1200-1300 DEG C, and the temperature of the bottom of the molten pool is 400-450 DEG C; and a sulfurizing agent is thrown and added into the molten pool to perform copper removal. The method further includes the step that cold charge is thrown and added into the molten pool from the top of the copper removal furnace, and the cold charge is lead with the copper content range being 0.03-0.06wt%. By throwing and adding the lead with the copper content range being 0.03-0.06wt% into the molten pool from the top of the copper removal furnace to serve as the cold charge, the copper content in the crude lead liquid is diluted and thus is reduced, the concentration of copper, originally located on the balance concentration liquid level for copper to separate out, in the crude lead liquid is reduced, copper in furnace accretion adhering to the inner wall is re-dissolved in the crude lead liquid, the furnace accretion is made to return and be molten again for furnace washing, and therefore generation of the furnace accretion is inhibited.
