Lanthanum Supply Chain: From Mine to Market

Lanthanum follows the standard rare earth supply chain with China producing ~62% of mine output and ~90% of separation capacity. It is the second most abundant light rare earth (after cerium), comprising ~25% of typical bastnasite/monazite ore content. Major end uses include petroleum FCC catalysts (~30% of demand), NiMH battery alloys, optical glass, and the pharmaceutical Fosrenol. Lanthanum faces a structural oversupply challenge similar to cerium: mining rare earths for neodymium inevitably produces lanthanum surpluses. Lynas Rare Earths and MP Materials are the main non-Chinese sources.

Production Geography

Global Lanthanum production is led by China, which accounts for approximately 62% of world output, followed by Myanmar. The full list of major producing nations includes China, Myanmar, Australia, United States. This geographic concentration means that disruptions in key producing regions can have outsized impacts on global supply and pricing.

Extraction Methods

Lanthanum is extracted using the following primary methods:

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

Processing and Intermediate Products

Lanthanum is primarily sourced from Bastnasite, Monazite, Ion-adsorption clays. After extraction, the raw material undergoes multiple processing steps including beneficiation, chemical treatment, and refining to reach the purity levels required by downstream industries. Typical ore grades range from 1-10% REO.

Key Supply Chain Participants

The Lanthanum supply chain involves these major companies:

Supply Chain Vulnerabilities

Key vulnerabilities in the Lanthanum supply chain include concentration of 62% of production in China, limited processing capacity diversification, and long lead times for new mining projects. The high supply risk rating reflects the severity of these concentration risks and the difficulty of rapidly establishing alternative supply sources.
