Embodiment 1

[0018] The raw material of this embodiment is the original copper-clad aluminum wire scrap with a diameter of 2 mm and a mass of 25 g, wherein the weight percentage (mass fraction) of copper is 33.3%. The raw copper-clad aluminum wire waste is leached with waste electrolyte to remove part of soluble impurities to obtain copper-clad aluminum bare wire waste.

[0019] The method of this embodiment is as follows:

[0020] ①Cut the copper-clad aluminum bare wire waste into a certain length (suitable for placing in the anode frame, 10cm in this embodiment).

[0021] see figure 1 , the first titanium mesh 21 is placed in the porous plastic anode frame 1 with a porosity of 40%, and the copper-clad aluminum bare wire scrap is placed on the first titanium mesh 21 to form a first stack of copper-clad aluminum bare wires 41. The first The adjacent copper-clad aluminum bare wire scraps in the stacked copper-clad aluminum bare wires 41 are in contact with each other, and the copper-clad ...

Embodiment 2

[0026] The method of the present embodiment is the same as the embodiment 1, and the difference is:

[0027] The diameter of the original copper-clad aluminum wire scrap is 1 mm and the mass is 250 g, and the plastic coating on the original copper-clad aluminum wire scrap is removed to obtain the copper-clad aluminum bare wire scrap. The electrolysis conditions and electrolysis results are shown in Table 1.

[0028] The anode device in step ① in this embodiment also has a second titanium mesh 22 and a copper-clad aluminum bare wire scrap placed on the second titanium mesh 22, and the copper-clad aluminum bare wire scrap placed on the second titanium mesh 22 is formed The second stack of copper-clad aluminum bare wires 42; the second titanium mesh 22 is placed on the top of the first stack of copper-clad aluminum bare wires 41, the bottom of which is in contact with the first stack of copper-clad aluminum bare wires 41, and the upper part is in contact with the second stack of ba...

Embodiment 3

[0031] The method of this embodiment is the same as that of embodiment 2, and the difference is: electrolysis conditions and electrolysis results (see Table 1).

Abstract

The invention discloses a method for recovering copper and aluminum from copper-clad aluminum conductor scrap and an anode device for the electrolytic equipment of the method. The method comprises the following steps of: (1) preparing the anode device of the electrolytic equipment, the anode device being provided with metal titanium part and copper-clad aluminum bare conductor separately contacting therewith; (2) adding electrolyte to the electrobath, putting a copper plate as a cathode to the electrolyte of the electrobath, and an anode devide as an anode to the electrolyte of the electrobath; and (3) electrifying direct current to electrolyze, stopping electrolyzing when the voltage of the electrobath being obviously increased, and recovering the aluminum in the anode device and copper on the copper plate. The invention can separate metal copper and aluminum of copper-clad aluminum conductor scrap by electrolysis, the needed equipment is simple, easy to operate and consumes little electric energy, and the cost is low.

Description

technical field [0001] The invention belongs to the field of metal recovery, and in particular relates to a method for recovering copper and aluminum from copper-clad aluminum wire waste and an anode device used in electrolysis equipment of the method. Background technique [0002] Copper has good electrical conductivity, its resistivity is 0.01851Ω·mm 2 / m, and the standard electrode potential of copper is high, and copper products will not be scrapped or invalid due to rapid corrosion in nature. Therefore, copper has long been regarded as the material of choice for the inner conductor of the cable. However, the density of copper is high, copper resources are relatively scarce, and the price of pure copper conductors is high. With the continuous development and progress of composite technology, the use of composite technology under the premise of ensuring electrical conductivity, replacing copper with cheap metal parts to reduce production costs, has become the goal of do...
