Abstract: The present invention relates to a method of producing carbon-coated lithium metal phosphate from a raw material containing lithium, comprising providing a solution containing lithium bicarbonate from an industrial process stream; reacting the lithium bicarbonate in the solution with metal ions, phosphate ions and a carbon source; separating the solids from the solution containing lithium bicarbonate by solid-liquid separation; and heat treating the solids to provide a carbon covered lithium metal phosphate. The method can be carried out continuously to produce lithium ion cathode chemicals in particular for the electrochemical industry, e.g. for ion cathode chemicals.
