Mining & Processing

How Cerium Is Mined and Processed

Cerium (Ce) is a rare earth element with global annual production of approximately 65,000 tonnes REO, primarily from China and Myanmar. Typical ore grades range from 1-10% REO (varies by ore type).

Mining Methods

Cerium 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 Cerium include:

• Bastnasite - (Ce,La(CO3)F)
• Monazite - (Ce,La,Nd,ThPO4)
• Ion-adsorption clays

Processing and Beneficiation

Following extraction, Cerium ore undergoes the following processing stages:

1. Acid cracking (bastnasite)
2. Alkali cracking (monazite)
3. Solvent extraction separation
4. Selective precipitation

Major Mines and Production Centers

The following are key Cerium mining and processing operations worldwide:

Environmental and Regulatory Considerations

Mining and processing of Cerium 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.
