Mixing Clarification Tank (Extraction Tank)
The MCT Series is a modular multi-stage mixing–clarification extraction system for continuous liquid–liquid extraction, washing and stripping. Each stage combines an agitated mixing zone with a dedicated settling compartment, enabling efficient mass transfer and high phase-separation performance in a compact footprint. MCT tanks are widely used in hydrometallurgy, rare-earth extraction, fermentation broth processing and environmental applications where stable phase disengagement and low solvent loss are critical.

Key Features:
Key Feature 1 — Modular multi-stage design
Configure extraction, wash and stripping stages in one train. Easy to expand capacity by adding stages.
Key Feature 2 — Continuous operation with stable phase disengagement
Dedicated settling zone and overflow weirs maintain a stable interface and reduce entrainment.
Key Feature 3 — Optimized mixing vs. emulsification
Controlled-turbulence mixing zone improves mass transfer while avoiding excessive shear that causes emulsions.
Key Feature 4 — Simple structure, easy maintenance
Easy access to mixer, weirs and internals for inspection and cleaning; ideal for multi-product campaigns.
Key Feature 5 — Corrosion-resistant material options
PVC/PP/PVDF or lined carbon steel / SS304/316L options to match acids, alkalis and solvent systems.
Working Principle :
Each stage consists of a mixing zone and a clarification (settling) zone:
Two immiscible phases (organic/aqueous) enter the mixing zone at a controlled ratio and are gently but efficiently mixed to complete mass transfer.
The dispersion flows into the clarification zone where turbulence is minimized; phases disengage by density difference and overflow through weirs.
Multi-stage connection enables counter-current extraction, counter-current washing, or stripping/back-extraction depending on your flowsheet.
Typical Applications (Industries) :
Hydrometallurgy & rare earth extraction (Cu/Ni/Co/Mn/Li, REE)
Battery materials & brine processing (extraction / washing / stripping)
Fermentation broth processing and environmental separation duties
Solvent-based purification processes where stable phase separation is critical
