ABSTRUCT Copper has good ductility, high thermal conductivity and high conductivity, which can form many kinds of alloy。 Copper alloy has excellent mechanical properties and low electrical resistivity, which is widely used。 The traditional copper electrolysis is the process of the crude copper (copper 99%) prefabricated plate as anode, made from pure copper sheet is used as cathode, with sulfuric acid (H2SO4) and copper sulfate (CuSO4) as the electrolyte, electrolysis to obtain electrolytic copper。 The design of this project is to copper electrolysis process calculation and groove design, including: electrolytic tank of the material and the structure of, determination of the total number of the electrolytic tank, selection and calculation of the cathode and the anode, electrolysis groove size, and drawing electrolytic tank installation diagram。 The results show that the design is used in copper。 Quality for the 6。01kg of the initial pole piece, 370kg anode film, the size of the electrolytic cell for 2200*1100*1290mm, outside the size of 2400*1300*1390mm。 The size of the anode plate is 100*96*45mm, the size of the cathode plate is 1020*1000*0。6mm。 The anode plate number is 20, the cathode plate number is 19, each center distance of 100, the current density is 260A/m2 and the slot number is 830。
80000t/a electrolytic refining of copper required number of copper anode for 99251。6066t, the amount of copper 98656。097t, the quantity of anode slime 57。1355377t, residual pole for 16771。5365t。 The number of copper removal slots is 9。
