The invention relates to a method and plant for the recovery of lithium carbonate from contaminated lithium bromide. The contaminated lithium bromide is heated and carbonate is added in order to principate lithium carbonate. The lithium bromide, being contaminated with metals and/or organic compounds. Metals such as Cu<2+>, Cr<3+>, Cr<6+>, Fe<2+> and Fe<3+> and/or organic compounds such as tensides, anticorrosive agents and antifoaming agents. The lithium carbonate is preferably recovered using sodium carbonate.
