Abstract: In a method of recovering an active metal of a lithium secondary battery, an acidic leaching liquid is added to a material to be recovered which contains a lithium metal oxide to form a mixture including a first active metal solution and a leached residue. The formed mixture is subjected to solid-liquid separation for separating the first active metal solution from the leached residue to form a second active metal solution. A lithium hydroxide aqueous solution containing an iron salt is added to the second active metal solution to form a third active metal solution from which impurities are removed or reduced. A lithium precursor is recovered from the third active metal solution.
