Single-Stage Solvent Extraction Unit for R&D and Small-Scale Production

The unit is designed for modeling and validating the technical feasibility of continuous solvent extraction processes using minimal material volumes. It is also suitable for low-throughput production of high-purity metal compounds.

Key Features
Single-stage mixer–settler (one extraction stage). Constructed from polypropylene, ensuring compatibility with the vast majority of solvent extraction systems.
Demountable housing with removable cover:
Simplifies assembly, reduces material use, eliminates organic/aqueous phase dead zones, and allows easy removal of solid residues.
Integrated pre-mixing chamber:
Located at the bottom of the unit and connected to the mixing zone via a flanged vertical nozzle for optimal phase contact.
Independent mechanical mixer and phase-transfer system within the mixing chamber.

Front-mounted interface:
All phase inlets/outlets, adjustable internal aqueous-phase recirculation, and process control elements are conveniently positioned on the front side for easy operation.

Flexible modular layout:
Units can be mounted on individual or shared frames and connected by flexible interstage overflow lines, allowing rapid assembly and disassembly of multi-stage extraction systems.
