Methods for the Extraction of Minerals with Rare Earths

Inefficient extraction of rare earths from complex ores leads to low yields, high pollution, and unsustainable operations. These issues can jeopardize compliance, raise costs, and hinder industrial performance. TYIC’s engineered extraction solutions offer advanced, customized systems that maximize efficiency while ensuring environmental safety.

Hangzhou Tianyicheng New Energy Technology Co., Ltd. (TYIC) specializes in designing and manufacturing tailored rare-earth extraction systems, including tubular mixing extractors, micro-interface oil removal units, and corrosion-resistant tanks—ensuring efficient recovery and regulatory compliance for industrial clients.

Explore how TYIC delivers optimized rare-earth extraction from complex ores through custom engineering and chemical technology.

Customized Equipment for Rare Earth Extraction

TYIC provides end-to-end engineered solutions for rare-earth mineral extraction, focusing on companies engaged in lithium battery recycling, non-ferrous metal processing, and environmental protection. With decades of expertise in chemical separation technologies, TYIC offers integrated systems that are efficient, reliable, and compliant with global environmental standards.

1. Physical Pre-treatment Systems

TYIC’s extraction process begins with equipment for ore pre-treatment and mineral separation. For rare-earth ores such as bastnäsite, monazite, or xenotime, our equipment suite includes:

• Tubular mixing extractors: Ensure homogeneous reagent contact for effective separation;

• Micro-interface oil removal systems: Remove organic impurities from flotation processes;

• High-performance plastic sheets and tanks: Enable corrosion resistance during acidic or alkaline pre-treatment phases.

These technologies help improve physical beneficiation steps, such as flotation and magnetic separation, by increasing mineral liberation and pre-concentrating rare earths before chemical processing.

2. Advanced Leaching and Extraction Systems

TYIC’s strength lies in chemical process design. We develop customized acid or alkali leaching systems tailored to the specific mineralogy of each ore body. Depending on client needs and regulatory context, we engineer:

• Closed-loop acid leaching systems: Designed with HDPE/PPH corrosion-resistant tanks and integrated neutralization units to handle sulfuric, hydrochloric, or nitric acid safely and efficiently;

• Alkaline digestion systems: For phosphate-based ores, enabling high leaching efficiency with minimized waste.

These leaching systems are integrated into full extraction lines, ensuring maximum metal recovery while reducing chemical consumption.

3. Modular Solvent Extraction and Purification Units

TYIC designs solvent extraction (SX) units customized for different rare-earth groups (light vs. heavy REEs). Our modular design philosophy ensures that clients can scale operations efficiently while maintaining high purity standards. Key features include:

• Multi-stage extraction columns: Achieve selective separation with high throughput;

• Automated control systems: Ensure stable process performance and real-time parameter adjustment;

• Material compatibility: All contact materials are chosen to resist acid and solvent corrosion for longevity.

We also offer ion exchange systems when lower volumes or niche elements require high-purity separation with minimized organic waste.

4. Integrated Waste Treatment and Compliance

TYIC integrates environmental protection into every project. Our waste gas and wastewater treatment systems ensure that effluent from rare-earth extraction meets local and international environmental standards. Core features:

• Gas scrubbing systems: Remove acid mists and volatile organic compounds (VOCs) generated during leaching or solvent extraction;

• Effluent neutralization and heavy metal removal: Treat acidic wastewater containing rare-earth impurities, thorium, or uranium residues;

• Solid waste encapsulation: Safely stabilize and store radioactive or hazardous residues from extraction tailings.

By including these systems, TYIC helps clients maintain ESG compliance and reduce their environmental footprint.

Engineering and Customization: TYIC’s Competitive Edge

As a full-scope EPC provider (Engineering, Procurement, Construction), TYIC goes beyond equipment supply to deliver process design, layout optimization, automation, and material selection. For rare-earth extraction projects, we offer:

• Pilot plant simulation and testing: Assess process feasibility using actual ore samples;

• Flow design and 3D modeling: Optimize footprint and integration with existing facilities;

• Remote monitoring and smart control: Enable real-time oversight of key process parameters.

Clients such as EcoPro (South Korea), Tianneng, and GEM have partnered with TYIC for rare-metal extraction projects, trusting our engineering excellence and project delivery track record.

Supporting Sustainability and Global Supply Chains

TYIC’s rare-earth extraction solutions support the circular economy and clean energy value chain. By partnering with lithium battery recyclers and non-ferrous metal refiners, we help ensure critical materials are efficiently recovered and reintroduced into the supply chain. This enhances material independence and supports the global transition to electric vehicles and renewable energy.

Our export footprint includes Southeast Asia, Europe, and North America, where TYIC systems are integrated into advanced material recovery and battery precursor production lines.
