A process for the removal of contaminants from a liquor, the process comprising a combination of carbonatation and phosphatation and optionally sulphitation occurring together to form precipitate comprising at least some of the contaminants from the liquor in a reaction vessel and separating the precipitate from the liquor, wherein the precipitate comprises particles that comprise both carbonate and phosphate and wherein the size of the particles is increased by feeding a portion of the liquor which has left the reaction vessel back into the reaction vessel.
