US patent US12728370

Methods and systems for organic recovery in solvent extraction

Abstract

A device for recovering entrained organic particles from an aqueous solution is provided. The device comprises a tank configured to receive a mixed solution through an inlet, wherein the mixed solution comprises an aqueous solution and organic particles, a plurality of curved impellers configured to impel a torque on the mixed solution, wherein in response to receiving the torque the mixed solution moves in a rotational motion within the tank, a deflector wall coupled to the floor extending vertically from the floor and surrounding the plurality of curved impellers to form an inner well configured to direct a flow of the rotating mixed solution towards a top surface of the tank, and a skim launder coupled to a boundary wall of the tank and positioned at the top surface, wherein the skim launder is configured to recover organic particles from the tank as they separate from the aqueous solution.
