    摘要: The present invention provides a process of recovering AB5 and/or AB2 as well as other metals from spent nickel metal hydride batteries from a slury by a series of separation steps utilizing the screening off of larger metal particles, removal of magnetizable small metal particles from a filter and then separating AB5 and/or AB2 by passing the filtrate through a froth flotation step to separate AB5 and/or AB2 from lighter small particles.
