Zusammenfassung:	F.973 PROCESS FOR REMOVING HUMIC MATTER FROM PHOSPHORIC ACID SOLUTIONS A process is disclosed for removing colloidal and non-colloidal humic matter from an aqueous solution of phosphoric acid, the process comprising (a) treating the phosphoric acid solution with a flocculant to flocculate the humic matter, (b) adding to the aqueous solution an effective amount of a phenol compound in order to destabilize the colloidal humic matter contained in the solution and to aid in the formation of froth, and (c) separating the humic matter from the solution by froth flotation.
