The process for treating sludge with copper import, disposes collaboratively the combined technology of copper smelting process and sludge with copper import fire disposal, including classification of copper sludge with different variety imports according to more than 2% and less than 2% sulfur standards, then treats by adopting varying means; the process carries out resource utilization of the vast majority sulfur in original materials in the production of sulfuric acid, reduces effectively flue gas SO2 pollution to environment, and improves significantly the recovery rate of valuable metals such as copper, reduce consumption of energy resources.
