Its advantages are short process, simple equipment, fast factory construction, and low investment. The metal copper obtained by blast furnace smelting has a high impurity content and is black, so it is copper clad steel strips manufacturer called black copper. The three-stage method has good comprehensive utilization of materials, simple smoke composition, simple treatment, high crude copper grade, simple furnace operation, and high equipment processing rate. However, it has more complicated processes, more equipment, and capital investment. The black copper is blown into sub-coarse copper in the converter, and the sub-coarse copper is refined into anode copper in the reverberatory furnace.
Three-stage method The mixed copper is first reduced and smelted into blast furnace by blast furnace. However, when this method deals with messy copper components, the smoke and dust components produced are messy and difficult to handle; the furnace operated together in a quintessential way is long, labor-intensive, and processing Low power and low metal recovery rate.. Because these two methods have to pass through two processes, it is called two-stage method.
Therefore, in addition to the manufacturers of large-scale membranes that need to deal with some special waste residues in China, the general waste and miscellaneous copper treatment process mostly uses two-stage method and one-stage method. It is then refined into anode copper in the reverberatory furnace.The distribution of aluminum bronze, the processing method of recycled copper is mainly the first, the waste mixed copper is directly smelted into copper alloys or refined copper of different brands, so it is also called the direct utilization method; second, the mixed copper is first processed into the anode by fire treatment Copper, then the essence of electrolysis into electrolytic copper and recover other valuable elements in the electrolysis process.
One-step method to directly divide the classified yellow or copper copper into the refined copper anode copper. When using the second method to deal with copper-containing waste, there are generally three different processes, namely, one-stage method, two-stage method and three-stage method.
