In cutting-edge fields such as semiconductors, new energy batteries, and aerospace, high-purity metals (such as cobalt, nickel, lithium, rare earth elements, etc) have become indispensable “industrial blood.” However, efficiently and sustainably extracting and refining these “metal treasures” from complex waste liquids, low-grade ores, or smelting intermediates has long been a major challenge for the industry. Traditional extraction processes often suffer from inefficiency, significant solvent loss through entrainment, difficulty in ensuring purity, and high operating costs.
Centrifugal Extraction Technology Leading the Transformation
As a core method for separating and purifying metal ions, solvent extraction directly determines the purity and economic viability of the final product. Tiei Extraction CWL-M centrifugal extractor represents a revolutionary piece of equipment in this field, setting a new benchmark for high-purity metal recovery.
The centrifugal extractor ingeniously integrates the principles of liquid–liquid extraction with a high-speed centrifugal force field:
1.Mixing and Mass Transfer: The metal-containing feed solution and the extractant are subjected to intense shearing and mixing inside the high-speed rotating drum, enabling rapid and efficient transfer of metal ions from the aqueous phase to the organic phase.
2.Centrifugal Separation: By harnessing the density difference between the two phases and the immense centrifugal force (hundreds to thousands of times gravity), the extraction phase and raffinate phase are separated instantly, cleanly, and thoroughly.
Advantages of the Centrifugal Extractor in High-Purity Metal Recovery
- Ultra-High Separation Efficiency and Purity
Millisecond-level mixing and second-level separation greatly shorten mass transfer time and minimize side reactions.
The revolutionary phase-separation performance virtually eliminates solvent entrainment (<10 ppm), preventing cross-contamination and ensuring the reliable production of ultra-high-purity metals at 5N (99.999%) and above. - Single-Stage Efficiency >95%, Significantly Reduced Stages
The extraction efficiency per stage far surpasses that of traditional mixer-settlers or extraction columns, drastically reducing the number of required stages, saving both equipment investment and plant space. - High Throughput with Small Footprint
With a compact, modular design, its processing capacity per unit area is several to dozens of times that of traditional equipment, making it especially suitable for space-constrained environments or rapid capacity expansion. - Extremely Low Solvent Retention
The small liquid hold-up inside the equipment significantly reduces the consumption and loss of costly extractants, while also lowering the risk of solvent degradation and ensuring long-term stable operation. - High Automation and Continuous Operation
Perfectly aligned with modern continuous production processes, it can be easily integrated into DCS control systems, enabling unattended operation or remote monitoring to enhance production stability and safety. - Strong Adaptability
Capable of easily handling systems prone to emulsification or with small phase density differences, thereby broadening the range of available feed sources.
