Patent number: 11519081Abstract: The present disclosure relates to a method for extracting lithium from a lithium-containing material. For example, the method can comprise leaching a roasted lithium-containing material under conditions suitable to obtain an aqueous composition comprising a lithium compound such as lithium sulfate and/or lithium bisulfate. The aqueous composition comprising lithium sulfate and/or lithium bisulfate can optionally be used, for example, in a method for preparing lithium hydroxide comprising an electromembrane process. The roasted lithium-containing material can be prepared, for example by a method which uses an aqueous composition comprising optionally lithium sulfate and/or lithium bisulfate which can be obtained from a method for preparing lithium hydroxide comprising an electromembrane process such as a two-compartment monopolar or bipolar electrolysis process.Type: GrantFiled: August 9, 2021Date of Patent: December 6, 2022Assignee: NEMASKA LITHIUM INC.Inventors: Jean-François Magnan, Guy Bourassa, Nicolas Laroche, Gary Pearse, Stephen Charles Mackie, Mykolas Gladkovas, Peter Symons, J.
