Solvent Extraction System
Solvent Extraction System
Solvent extraction is a crucial process in battery recycling that follows chemical leaching. After valuable metals are dissolved in a leaching solution, solvent extraction is employed to selectively separate and concentrate these metals from the solution. This method is particularly effective in recovering metals like cobalt, nickel, and lithium from battery materials.
A specific organic solvent is chosen based on its ability to selectively bind with the desired metals. The solvent forms a complex with the target metals while leaving impurities behind. The leachate and the solvent are mixed together in an extraction unit. The solvent’s complexing agents selectively bind to the dissolved metals, forming metal-rich organic compounds. The mixture is then allowed to settle, leading to phase separation. The organic phase containing the metal-rich complexes separates from the aqueous phase, which contains impurities and unreacted reagents. The metal-rich organic phase is transferred to a stripping unit, where the metals are selectively stripped from the solvent using a suitable solution. This solution typically has a high acidity or another reagent that releases the metals from the complex. The stripped solution, often referred to as the “loaded strip,” contains the concentrated metals. This solution can be further processed for refining, and the solvent can be regenerated for reuse in future extraction cycles.
Solvent Extraction Systems commonly utilize Mixer-Settlers for liquid-liquid extraction applications. These systems operate in continuous mode and consist of two stages. The first stage involves mixing the two liquid phases to facilitate mass transfer, while the second stage uses gravity for natural separation and settling of the phases. Mixer-Settlers can be integral or separate and operate either continuously or in batches. A scrubbing step is employed to clean the leach solution from impurities, followed by recovery of rare metals using appropriate organic solvents. Precipitation is performed, and the resulting solid is filtered to obtain the desired form of the recovered materials.
The Mixer-Settler technology we employ ensures efficient mass transfer, resulting in precise separation of metals. Our Solvent Extraction Systems can be tailored to fit different operational preferences and requirements, ensuring flexibility. With a commitment to quality, our scrubbing step effectively removes impurities, producing materials of exceptional purity.
