摘要： Valuable metals such as cobalt, nickel, manganese, and lithium can be economically recovered from various lithium secondary battery-related wastes by the inventive method which comprises liquid-phase leaching a scrap powder containing Co, Ni, Mn, and Li, and purifying and solvent-extracting the resulting leaching solution to recover each of said Co, Ni, Mn, and Li, wherein the liquid-phase leaching is performed by a two-step counter-current leaching using an inorganic acid solution or a mixed solution of an inorganic acid and hydrogen peroxide.
