Abstract
The present invention relates to the recovery and purification of lithium from lithium containing sources, like lithium ion battery materials, using ion exchange. A lithium salt containing solution is passed through an acid cation exchange resin, and a lithium raffinate and a mixture of other elements such as metals like nickel, cobalt and manganese, are recovered as products. The lithium raffinate can then be processed into other lithium products such as lithium carbonate and lithium hydroxide.
