TYIC’s Hydrometallurgical Workflow for REE Separation

Feed Preparation and Leaching
TYIC customizes its leaching equipment (tubular extractors, micro-interface reactors) based on the mineralogical characteristics of the feedstock—whether monazite, bastnaesite, or recycled battery black mass. Acidic (HCl, H₂SO₄) or alkaline leaching solutions are selected to optimize rare earth dissolution and minimize radioactive or toxic impurity release.
Impurity Removal and Pre-Treatment
Through integrated solid-liquid separation and targeted precipitation systems, TYIC removes iron, aluminum, calcium, and other matrix elements from the pregnant leach solution. This reduces the burden on downstream solvent extraction stages and enhances final product quality.
Solvent Extraction Systems (SX)
TYIC designs multi-stage solvent extraction circuits with high-efficiency phase mixers and separators. These systems use advanced phosphinic or carboxylic extractants to selectively separate individual rare earths like Nd, Pr, Dy, and Tb. Automation ensures accurate pH control and phase flow, critical for separation of closely related lanthanides.
Ion Exchange and Refinement
For high-purity needs or to supplement SX limitations, TYIC offers ion exchange columns using rare earth-selective resins. These are especially effective for heavy REE recovery. Modular configurations allow clients to integrate ion exchange into existing flowsheets seamlessly.
Precipitation and Final Processing
TYIC supplies closed-loop precipitation systems (e.g., oxalate, carbonate, or hydroxide) that convert REE-rich solutions into solid products. Final calcination equipment produces REE oxides meeting 99.9%+ purity requirements for magnet and phosphor applications.
Wastewater and Byproduct Management
As an environmental technology leader, TYIC integrates its proprietary wastewater and gas treatment systems into the REE process line. Clients benefit from reduced chemical discharge, recycled process water, and compliance with China and international emission standards.
