Neodymium Supply Chain: From Mine to Market

Neodymium is the most commercially important rare earth element. China produces ~62% of mined rare earth output and controls ~90% of NdPr separation and ~92% of NdFeB magnet production. The supply chain runs from mining through cracking, solvent extraction separation (NdPr oxide), metal reduction (molten salt electrolysis), alloy strip casting (Nd2Fe14B), and magnet manufacturing (sintering or bonding). China dominates every stage. The critical chokepoint is the combination of separation and magnet manufacturing: even if Western mines produce concentrate, converting it to magnets requires technology and capacity that China has restricted via 2023 export controls on processing technologies. Lynas, MP Materials, and Arafura are building non-Chinese capacity but the West remains years behind in establishing a complete mine-to-magnet supply chain.

Production Geography

Global Neodymium 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

Neodymium is extracted using the following primary methods:

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

Processing and Intermediate Products

Neodymium 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 (Nd is ~18% of light REE content).

Key Supply Chain Participants

The Neodymium supply chain involves these major companies:

Supply Chain Vulnerabilities

Key vulnerabilities in the Neodymium 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.
