    Abstract: A method and arrangement for recovering lithium carbonate from a raw material containing lithium, which method comprises pulping (1) the raw material containing lithium in the presence of water and sodium carbonate for producing a slurry containing lithium from the raw material containing lithium. After pulping the lithium-containing slurry is leached (2) for dissolving the lithium in the solution thus producing a solution containing lithium carbonate. After pulping and leaching the method comprises carbonating (3) the solution containing lithium carbonate by using carbon dioxide under atmospheric conditions for producing a solution containing lithium bicarbonate and separating (4) the solids form the solution. The solution containing lithium bicarbonate is purified (5) to produce a purified solution containing lithium bicarbonate, and recovering by crystallising (6) lithium carbonate from the purified lithium bicarbonate-containing solution.

    Abstract: A method and device for producing polyphosphoric acid burns a fuel in combustion air in a combustion chamber, sprays a spray fluid comprising substantially pure orthophosphoric acid and undertakes polymerization-condensation of the pure orthophosphoric acid. A polyphosphoric acid in the form of an acid mist accompanied by formation of gases which mix with combustion gases resulting from burning of the fuel is formed to reach a predetermined temperature, wherein the mixture causes sudden lowering of combustion gas temperature. The acid mix is separated from the gas mixture and the polyphosphoric acid is collected at a bottom of the combustion chamber and the gas mixture is outputted via a lower part of the combustion chamber separate from the collection of polyphosphoric acid.
