In high-end industries such as semiconductors, OLED, DRAM, sensors, and hydrogen energy, the demand for platinum group metals (PGMs) such as ruthenium, iridium, and platinum continues to grow. Their supply is highly concentrated in South Africa and Russia, while ruthenium and iridium are mostly obtained as by-products, making capacity expansion difficult. For the industrial supply chain, efficient purification and recovery are key to unlocking the value of these metals.
Solvent extraction is a commonly used method for platinum group metal purification. By selecting suitable extractants, platinum group metals can be extracted from mixed solutions, enabling their separation from other impurities. This method features simple operation and good separation performance and is widely used in industrial production. In actual production, the phase separation speed, residence time, solvent loss, and level of automation of the extraction equipment directly affect purification efficiency and operating costs.
The CWL-M Centrifugal Extractor is a new, efficient, energy-saving, and automated extraction and separation equipment. It uses centrifugal force to enhance mixing and phase separation. It features short single-stage residence time, rapid phase separation, high extraction efficiency, reduced investment costs, and lower solvent recovery and regeneration costs, playing an important role in platinum group metal purification.
Key Advantages of the CWL-M Centrifugal Extractor
1.Short single-stage residence time: Reduces prolonged contact between high-value process solutions and extractants, lowering the risks of degradation and entrainment.
2.Rapid phase separation: Centrifugal force enhances phase separation, making the equipment suitable for systems that are difficult to separate and improving clarification efficiency.
3.High extraction efficiency: Can be used with multi-stage counter-current or continuous operation to improve the recovery rate and purity of platinum group metals.
4.Reduced solvent consumption: More efficient solvent circulation and reuse help reduce solvent recovery and regeneration costs.
5.Automated continuous operation: Stable operation is suitable for continuous industrial production and reduces manual intervention.
6.Compact structure: Saves floor space and investment costs, and facilitates system integration.
Applications in Platinum Group Metal Purification
The CWL-M Centrifugal Extractor can be used for extraction, stripping, washing, and separation processes in platinum group metal purification, helping achieve effective separation of ruthenium, iridium, platinum, and other metals from impurities, and providing stable support for subsequent refining and high-end material production.
For platinum group metal systems with complex compositions, high-value process streams, and costly extractants, centrifugal extraction technology can improve separation efficiency, reduce solvent loss, and enhance batch-to-batch stability. Whether used for platinum group metal refining, precious metal recovery, or high-end material production, the CWL-M Centrifugal Extractor provides reliable support for continuous and automated process operations.
Conclusion
As high-end manufacturing continues to develop, its dependence on platinum group metals such as ruthenium, iridium, and platinum is becoming increasingly significant. Unlocking the value of platinum group metals depends on efficient and stable purification and separation technologies. With its advantages of high efficiency, energy saving, and automation, the CWL-M Centrifugal Extractor provides a reliable equipment solution for platinum group metal purification.
