Abstract
The present disclosure provides a new method capable of efficiently collecting Ni, Co, and Mn from battery waste containing Ni, Co, and Mn. A method for recycling a positive electrode material according to the present disclosure includes: a Mn leaching step of leaching Mn into an aqueous phase by performing ammonia leaching on battery waste containing Ni, Co, and Mn under a condition that a Mn leaching rate is 70% or more, and a ratio of the Mn leaching rate is 65% or more with respect to a total of a Ni leaching rate, a Co leaching rate, and the Mn leaching rate; and a Ni and Co leaching step of leaching Ni and Co into an aqueous phase by performing ammonia leaching on a solid residue obtained in the Mn leaching step under a condition that a Mn leaching rate is less than 1%.
