一是將廢雜銅直接熔煉成不同牌號的銅合金或精銅，所以又稱直接利用法； First, the scrap copper will be directly melted into different grades of copper alloy or refined copper, so it is also called direct profit. 二是將雜銅先經火法處理鑄成陽極銅，然后電解精煉成電解銅并在電解過程中回收其他有價元素。用第二類方法處理含銅廢物時，通常又有 3 種不同的流程，即一段法、二段法和三段法。 The two is to treat the miscellaneous copper by means of fire treatment, and then to electrolysis and refine it into electrolytic copper and recover other valuable elements in the process of electrolysis. When treating waste containing copper in second ways, there are usually 3 different processes, one stage method, two stage method and three stage method. 一段法 將分類過的黃雜銅或紫雜銅直接加進反射爐精煉成陽極銅的方法。其優點是流程短、設備簡單、建廠快、投資少，但該法在處理成分復雜的雜銅時，產出的煙塵成分復雜，難以處理；同時精煉操縱的爐時長，勞動強度大，生產效率低，金屬回收率也較低。 The first step is to directly mix the classified brass or purple copper into the anode furnace to refine the anode copper. Its advantages are short process, simple equipment, fast construction and less investment, but when the complex copper is treated, the composition of the produced smoke and dust is complex and difficult to be treated. At the same time, the refining furnace is long, the labor intensity is large, the production efficiency is low, and the recovery rate of metal is low. 二段法 雜銅先經鼓風爐還原熔煉得到金屬銅．然后將金屬銅在反射爐內精煉成陽極銅；或雜銅先經轉爐吹煉成粗銅．再在反射爐內精煉成陽極銅。由于這兩種方法都要經過兩道工序，所以稱為二段法。鼓風爐熔煉得到的金屬銅雜質含量較高，呈玄色，故稱為黑銅。 Copper is obtained by reduction and smelting of the two section method of copper in a blast furnace. Then the metal copper is refined into the anode copper in the reverberatory furnace; or the copper is blown into copper by the converter first, and then refined into the anode copper in the reverberatory furnace. Because these two methods have to go through two processes, they are called two sections. The content of metal copper impurity in blast furnace smelting is high, and it is black, so it is called black copper. 三段法 雜銅先經鼓風爐還原熔煉成黑銅，黑銅在轉爐內吹煉成次粗銅，次粗銅再在反射爐中精煉成陽極銅。原料要經過 3 道工序處理才能生產出合格的陽極銅，故稱三段法。三段法具有原料綜合利用好，產出的煙塵成分簡單、輕易處理、粗銅品位較高、精煉爐操縱較輕易、設備生產率也較高等優點，但又有過程較復雜、設備多、投資大且燃料消耗多等優點。因此，我國除規膜較大的企業或需處理某些特殊廢渣外，一般的廢雜銅處理流程多采用二段法和一段法。 The three stage method copper is first reduced to smelt black copper by blast furnace, and black copper is blown into secondary copper in the converter, and then the crude copper is refined into anode copper in the reverberatory furnace. The raw material needs 3 processes to produce qualified anode copper, so it is called the three stage method. The three section method has the advantages of comprehensive utilization of raw materials, simple composition of the produced smoke and dust, easy treatment, high grade of crude copper, easy manipulation of the refining furnace and higher equipment productivity, but it has many advantages, such as complicated process, large equipment, large investment and more fuel consumption. Therefore, in addition to the large enterprises with special regulations or special waste disposal, the general waste copper treatment process usually adopts the two stage method and the one stage method.
