The invention provides a technical scheme for recycling valuable metal from waste lithium-ion batteries by a wet method. By the technical scheme, the separation effect can be improved, least waste liquid is generated to reduce cost, and equipment utilization is increased. According to the scheme, the recycling rate of aluminum in a first-grade product can be over 99 percent, the concentration of a copper sulfate solution is 45-55g/L, the concentration of a cobalt sulfate is 115-125g/L, and the concentration of a nickel sulfate solution is 85-95g/L. |
