Introduction: Why Mixer Settler Technology Matters in Modern Hydrometallurgy

As global demand for critical metals such as lithium, cobalt, nickel, copper, and manganese continues to rise, hydrometallurgical solvent extraction has become a key technology for sustainable metal recovery from:

• Spent lithium-ion batteries
• Printed circuit boards (PCBs)
• Alkaline and zinc batteries
• Secondary metal resources

Among all solvent extraction equipment types, the mixer settler system remains one of the most reliable, scalable, and industrially proven solutions.

To support laboratory research and industrial scale-up, we provide a 5-stage laboratory mixer settler, specifically designed for continuous counter-current solvent extraction studies.

What Is a Laboratory Mixer Settler?

A mixer settler is a liquid-liquid extraction device consisting of:

1. Mixing chamber – where mass transfer occurs
2. Settling chamber – where organic and aqueous phases separate

A 5-stage mixer settler system simulates industrial multi-stage counter-current extraction under controlled laboratory conditions.
It is widely used in:

• Hydrometallurgical laboratories
• Metallurgical universities
• Research institutes
• Battery recycling R&D centers
• Engineering companies developing solvent extraction plants
• Applications in Lithium-Ion Battery Recycling and E-Waste Processing

Our laboratory mixer settler is ideal for:

• Lithium-Ion Battery (LIB) Recycling
• Cobalt (Co) / Nickel (Ni) separation
• Manganese (Mn) removal
• Lithium (Li) purification
• Impurity control
• PCB and Electronic Waste Recycling
• Copper solvent extraction
• Base metal separation
• Hydrometallurgical refining studies
• Alkaline Battery and Zinc Recovery
• Zinc (Zn) extraction
• Manganese purification
• Heavy metal separation

Why Choose Mixer Settler Instead of Extraction Column?

1. For many hydrometallurgical applications, mixer settler systems offer:
2. Stable hydraulic control
3. Easy maintenance
4. Flexible stage configuration
5. Clear phase interface observation
6. Better handling of complex leach solutions
7. Especially in lithium battery recycling, where feed composition may fluctuate, mixer settlers provide superior operational flexibility.
