A method for recovering Co, Ni, Mn and other valuable metal from lithium battery slag from ternary system Li metallic salt; the method comprises: stirring to dip out the lithium battery slag of lithium acid metallic salt comprising equal Co, Ni and Mn by diluted hydrochloride with hydrochloric acid concentration above 250g/l, or heating to 65-80 DEG C. and stirring to dip out by diluted sulfate with sulfate concentration above 200g/l, extracting the solvent of the leaching solution by acidic extractant to extract about 100% of Mn and Co metal so as to generate the liquid containing the metal and recover the corresponding metal from the liquid. |
