The variety of scrap copper is complex, and the recovery and use skills and processes are different, but they are generally divided into two parts: pretreatment and recycling. The so-called pre-treatment is to classify the thick and turbid waste copper, select other wastes mixed mechanically, remove the oil stain on the surface of the waste copper, and finally obtain a relatively pure waste copper of single variety, provide excellent materials for smelting, and then simplify the smelting process.
