  • Method for the hydrometallurgical recovery of lithium, nickel and cobalt from the lithium transition metal oxide-containing fraction of used galvanic cells
    Patent number: 9702024
    Abstract: A method for the hydrometallurgical recovery of lithium from a lithium transition metal oxide containing fraction of used galvanic cells is disclosed. According to the method, the lithium transition metal oxide containing fraction is introduced into sulphuric acid or hydrochloric acid, and hydrogen peroxide is added in an amount that is at least stoichiometric relative to the transition metal content to be reduced of the lithium transition metal oxide-containing fraction.
    Type: Grant

    Assignee: Rockwood Lithium GmbH
    Inventors: David Wohlgemuth, Mark Andre Schneider, Rebecca Spielau, Johannes Willems, Martin Steinbild
  • Method for the hydrometallurgical recovery of lithium from the fraction of used galvanic cells containing lithium, iron and phosphate
    Patent number: 9677153
    Abstract: A method for the hydrometallurgical recovery of lithium from the fraction of used galvanic cells containing lithium, iron and phosphate is disclosed. According to the method, lithium-iron-phosphate-containing fraction is introduced into sulfuric acid and/or hydrochloric acid, and hydrogen peroxide is added in an amount that is at least stoichiometric relative to the iron content to be oxidized of the lithium-iron-phosphate-containing fraction.
