Abstract
A solid component of a solid composition admixed with an aqueous medium is recovered by clarification and extraction in a common apparatus. An organic solvent for the solid component is admixed with the solid composition in the presence of the aqueous medium and the organic solvent is clarified in the apparatus by filtration with a filter which is not degraded by the organic solvent.
