Starting method for zinc hydrometallurgy of high-copper-content electrolyte

The invention discloses a starting method for zinc hydrometallurgy of a high-copper-content electrolyte, and belongs to the technical field of zinc hydrometallurgy electrodeposition. The method mainly comprises the following steps: fully circulating electrolyte before starting up; a cathode plate is arranged in the electrolytic bath, so that the electrolytic bath forms a circuit loop; supplying direct current; the direct-current power supply amount is gradually increased to meet normal production requirements; after the capacitor is turned on, the temperature of the electrolyte is kept below 32 DEG C within 4 hours; the acid content of the electrolyte is kept below 195 g/l; the precipitation condition is observed, and if the plate burning phenomenon does not exist, normal electrodeposition production can be carried out; observing a plate burning phenomenon in precipitation; adding a large amount of new solution to replace the circulating electrolyte; and after it is observed that cathode zinc is normally sepa
