At present, there are two important methods for producing recycled copper in China: the first type is copper alloy or fine copper which indirectly smelts waste copper into divergent trademarks, so it is also called indirect application method; the second type is to pass the copper through the fire. The method is to process the anode copper. After that, the electrolysis is refined into electrolytic copper and takes over the remaining valuable elements in the electrolysis process. When using the second type of method to dispose of copper-containing scrap, there are three different processes on weekdays, namely one-stage, two-stage and three-stage. l One method is to indirectly add the classified brass or copper to the reverberatory furnace to form the anode copper. The advantages are short process, simple equipment, fast construction, and low investment. However, when the method deals with complicated copper, the produced soot is complicated and difficult to handle. At the same time, the furnace is controlled by the essence, the labor intensity is large, and the production is high. Low efficiency and low metal acceptance rate. 2. The second-stage method of copper is firstly recovered by blast furnace to obtain metal copper. 2. Afterwards, the metal copper is refined into an anode copper in a reverberatory furnace; or the copper is first blown into a thick copper by a converter. It is then refined into an anode copper in a reverberatory furnace. Because these two methods have to go through two processes, so it is called the two-stage method. The metal copper obtained by smelting furnace smelting has a high impurity content and is black, so it is called black copper. 3 The three-stage method of copper is firstly smelted into black copper by a blast furnace, and the black copper is blown into secondary blister copper in the converter, and the second blister copper is then refined into anode copper in the reverberatory furnace. The material has to be processed through three processes to produce a good anode copper, so it is called the three-stage method. The three-stage method has a comprehensive application of materials, and the produced soot components are simple, freely sloppy, with high grades of coarse copper, superior sloppy control, and high productivity of equipment. However, the process is more complicated and equipped. The advantages of large investment and high fuel consumption. Therefore, in addition to the large-scale enterprises in China or the disposal of certain special wastes, the same two-stage method and one-step method are adopted.
