The invention provides a separation and recovery method for leaching solutions of waste battery material containing nickel, cobalt and manganese. The method comprises the steps of adopting trialkyl hydroxamic acid for extracting solutions to be treated for obtaining organic phases 1 and aqueous phases 1, wherein the nickel and the cobalt are extracted into the organic phases 1, and manganese ions and lithium ions are left in the aqueous phases 1; adopting sulfuric acid or hydrochloric acid for carrying out reverse extraction on the organic phases 1 for obtaining organic phases 2 and aqueous phases 2, wherein the nickel and the cobalt are reversely extracted into the aqueous phases 2; adopting a second extraction agent for extracting the aqueous phases 2 for obtaining organic phases 4 and aqueous phases 4, wherein the cobalt is extracted into the organic phases 4 and the nickel is left in the aqueous phases 4 for forming nickel solutions; adopting the sulfuric acid or hydrochloric acid for carrying out reverse extraction on the organic phases 4 for obtaining cobalt solutions; adopting a third extraction agent for extracting the aqueous phases 1 for obtaining organic phases 5 and aqueous phases 5 after phase splitting, wherein the manganese is extracted into the organic phases 5 and the lithium ions are left in the aqueous phases 5; adopting the sulfuric acid or hydrochloric acid for carrying out reverse extraction on the organic phases 5 for obtaining manganese solutions.
