Geochemistry and Elemental Analysis

Rare earth elements (REEs) are crucial to accomplishing renewable energy targets throughout the world, including electrical vehicles and wind energy. Despite the extensive requirements of REEs, current supply chains are mainly fulfilled by the Chinese rare earth (RE) industry. This has resulted in price volatility, supply chain uncertainties, and RE trade disputes. The authors identified 13 factors as constraints to develop RE supply chains outside China and these constraints were rated by the major RE companies outside China, including RE industry experts. The survey results obtained from RE industry experts have been statistically analysed to ascertain the key factors that affect the development of independent rare earth (RE) supply chains outside China. 4 key factors were identified as statistically important, among them, business uncertainties within the RE industry and the Chinese RE influences on global supply chains being the dominant factors.
