Mixer-Settler for Solvent Extraction and Purification
For solvent extraction processes requiring longer residence times, a mixer-settler system provides efficient phase separation while ensuring optimal mass transfer. Whether purifying precious metals, rare earth elements, or high-purity chemicals, the mixer-settler method allows for precise control over solvent contact and separation.
High-Efficiency Liquid-Liquid Separation for Extended Contact Time
The Type MD mixer-settler from Rousselet Robatel is engineered for continuous solvent extraction, washing, and purification processes. Unlike centrifugal extractors, which rely on high-speed separation, this system utilizes mechanical mixing followed by gravity-based phase settling, ensuring longer contact time for enhanced mass transfer.
Designed for applications in hydrometallurgy, nuclear processing, and chemical purification, the Type MD provides stable separation of organic and aqueous phases, acids, and reactive solvents. The system’s adjustable mixing parameters allow operators to optimize extraction efficiency for different chemical compositions.
The mixer-settler is built with modular compartments, allowing multiple extraction and washing stages to be configured in series. Its stainless steel and corrosion-resistant alloy construction ensures durability, even in harsh processing environments.
