Abstract:
1. A precipitation method of at least one solute, comprising: mixing of a first liquid phase containing the solute and a second liquid phase containing a reagent causing the solute to precipitate in a vessel, stirring of the mixture and removal of the precipitate, confining the mixture in emulsion in a third, chemically inert, liquid phase, non-miscible with the first liquid phase and the second liquid phase, the first liquid phase and the second liquid phase circulating in the vessel in a first direction, and the third liquid phase circulating in the vessel in a second direction opposite the first direction, wherein the mixture is stirred by a stirrer mobile in the vessel, a space separating the stirrer and an internal wall of the vessel, a width of said space being adjusted to establish a flow comprising a plurality of vortices continuously moving away and approaching the stirrer and the internal wall of the vessel, the plurality of vortices being aligned in said space separating the stirrer and the internal wall of the vessel, the first liquid phase and second liquid phase being included as droplets inside the third liquid phase in the plurality of vortices.
