Abstract
A manganese-lithium separation process and a pre-extraction solution preparation process in comprehensive recovery of ternary battery wastes, and a method for comprehensive recovery of cobalt, nickel, manganese and lithium elements from the ternary battery wastes, relates to a method for recycling battery wastes. According to the present disclosure, cobalt and nickel ions are separated from an impurity-removed solution by a hydrolysis method; manganese, lithium and other ions in the impurity-removed solution are free from an extraction procedure, so that most manganese ions are separated and removed by a wet method before extraction, to prevent the manganese ions from entering the extraction system; nickel ions are free from an extraction procedure of full extraction and full back-extraction; and nickel hydroxide is directly precipitated after related impurities are removed by extraction.
