Mining & Processing

How Neodymium Is Mined and Processed

Neodymium (Nd) is a rare earth element with global annual production of approximately 35,000 tonnes REO, primarily from China and Myanmar. Typical ore grades range from 1-10% REO (Nd is ~18% of light REE content).

Mining Methods

Neodymium is extracted through the following methods, selected based on deposit type and geology:

• Open-pit mining
• Underground mining
• Ion-adsorption clay leaching

Ore Types and Mineralogy

The principal ore types and mineral sources for Neodymium include:

• Bastnasite
• Monazite
• Ion-adsorption clays

Processing and Beneficiation

Following extraction, Neodymium ore undergoes the following processing stages:

1. Acid/alkali cracking
2. Solvent extraction
3. Molten salt electrolysis (metal production)

Major Mines and Production Centers

The following are key Neodymium mining and processing operations worldwide:

Environmental and Regulatory Considerations

Mining and processing of Neodymium must comply with environmental regulations governing water use, tailings management, emissions, and land rehabilitation. Increasingly stringent environmental standards are raising production costs but also driving innovation in cleaner extraction technologies. The social license to operate and community engagement have become critical factors in project development, particularly in China where 62% of global production is concentrated.
