  • PROCESSES FOR TREATING AQUEOUS COMPOSITIONS COMPRISING LITHIUM SULFATE AND SULFURIC ACID
    Publication number: 20220032207
    Abstract: The present disclosure relates to processes for treating an aqueous composition comprising lithium sulfate and sulfuric acid. The processes comprise evaporatively crystallizing the aqueous composition comprising lithium sulfate and sulfuric acid under conditions to obtain crystals of lithium sulfate monohydrate and a lithium sulfate-reduced solution; and optionally separating the crystals of the lithium sulfate monohydrate from the lithium sulfate-reduced solution. The processes optionally further comprise concentrating the lithium sulfate-reduced solution under conditions to obtain an acidic condensate and a concentrate comprising sulfuric acid.
    Type: Application
    Filed: August 9, 2021
    Publication date: February 3, 2022
    Applicant: NEMASKA LITHIUM INC.
    Inventors: Jean-François MAGNAN, Guy BOURASSA, Nicolas LAROCHE, Bertin OUELLET, Clive BRERETON, Steven BUCHI, Tsuki NAKA
