description The invention provides a method for diluting copper-containing sludge. A device adopted by the dilution method comprises a dilution processing device and a wire feeding device, wherein the dilution processing device takes electric heat or plasma heat as a heat source, and the dilution processing device is provided with a feeding port, a wire feeding hole and a matte discharge port. The dilution method comprises the following steps: drying the copper-containing sludge to obtain a dry material, wherein the water content of the dry material is less than or equal to 20%; and adding the dry material and a slagging agent into the dilution processing device through the feeding port, feeding a carbon powder wire into the dilution processing device through the wire feeding hole by using the wire feeding device, and reducing and diluting the dry material by using the carbon powder wire, wherein the iron-silicon ratio in the slagging agent is 0.4-0.8, and the calcium-silicon ratio is 0.6-0.9.
