hydrometallurgy process of lithium ore

  • What is hydrometallurgical lithium recycling?
    Li-Cycle''s hydrometallurgical recycling technology retrieves lithium, nickel, cobalt, and other metals from black mass. It produces these metals at such a high grade that they can be used to create new batteries.
