<p>The present invention relates to a method for obtaining a purified solid powder from highly concentrated, semi-liquid, high viscous solutions containing one or more solutes and a first solvent. The method comprises contacting the highly concentrated solution with a second solvent under high shear mixing, wherein the second solvent is miscible with the first solvent and wherein the solute has very low solubility or no solubility at all in the second solvent. Thereby a suspension of purified fine particles is obtained which can be easily separated to obtain a fine powder of the solute.</p> |
