Embodiment 1
[0028] Follow the steps below to pretreat high-tin copper anode slime:
[0029] Take 500g of high-tin copper anode slime, containing 22.4% by weight of tin on a dry basis, 11.1% by weight on a dry basis of copper, 3.5% by weight of nickel on a dry basis, and 9.3% by weight of antimony on a dry basis.
[0030] (1) Add high-tin copper anode slime into water according to the solid-liquid ratio S / L of 1 / 3 (g / mL), then put the mixture of high-tin copper anode slime and water into an ultrasonic generator with a frequency of 20kHz, Ultrasonic treatment for 15 minutes under the condition of sound energy density of 0.1W / mL, stirring and washing at 30°C for 30 minutes to remove the copper electrolyte after taking it out, and separating the washing solution and washed high-tin copper anode slime;
[0031] (2) Return the washing solution to the copper electrolysis system, and grind the washed high-tin copper anode slime into a particle size of 200 mesh anode slime powder;
