Method for separating and recycling copper and bismuth in arsenic-containing copper bismuth slag through ultrasonic reinforcement

The invention discloses a method for separating and recovering copper and bismuth in arsenic-containing copper-bismuth slag through ultrasonic reinforcement, which comprises the following steps: removing arsenic from the arsenic-containing copper-bismuth slag generated by copper smelting through an alkaline process to separate arsenic from copper and bismuth, carrying out reinforcement treatment on alkaline leaching slag slurry and an oxidant by adopting ultrasonic waves, adding part of copper leaching liquid into alkaline leaching liquid, neutralizing and precipitating arsenic through oxidation, and carrying out ultrasonic treatment to obtain copper-bismuth-containing slag; blowing air into the residual copper leaching solution, dropwise adding hydrogen peroxide to the bottom of the copper leaching solution for oxidation, and neutralizing with ammonia water to realize low-cost separation of copper and iron, acidifying the generated ferric hydroxide precipitate, and then returning to an ultrasonic strengtheni
