Aspects Of Light Rare Earth Element Resources, Bayan Obo, China By David M. Sutphin and Lawrence J. Drew Abstract In this report, the light rare earth oxides are defined and their use in metallurgy, magnets, ceramics, electronics, chemicals, and other applications is : D.M. Sutphin, L.J. Drew. China is the world’s leading rare earth element (REE) producer and hosts a variety of deposit types. Carbonatite-related REE deposits, the most significant deposit type, include two giant deposits presently being mined in China, Bayan Obo and Maoniuping, the first and third largest deposits of this type in the world, by: The Rare Earth Elements: Demand, Global Resources, and Challenges for Resourcing Future Generations light and heavy rare earth elements (LREE and mines at Bayan Obo and Maoniuping in China.
In China, the rare earth elements are also recovered as a by-product of iron mining. The world’s largest light rare earth deposit is Bayon Obo located in Baotou, China, containing 48 million tonnes of rare earths reserves in the form of bastnasite ore [ 22, 24 ]. Bastnasite ore concentrate is typically calcined to drive off CO 2 and fluorine. Currently, the rare earth supply in China mainly comes from the Bayan Obo REE–niobium–iron deposit situated in Inner Mongolia, the ion adsorption rare earth deposits in Jiangxi, Guangdong, Fujian, and Guangxi, the Mianning bastnaesite deposit in Sichuan and the Weishan bastnaesite deposit in Shandong, and the placer monazite and xenotime deposits in . RE mine in China, Bayan Obo, that might open up the possibility of recycling rare-earth residue as sustainable thorium resources. free download until 4 Oct Within a few years of the formation of Baotou, China began rare earth concentrate production at Bayan Obo, marking the start of today’s dominant rare earth industry. China’s specific costs related to rare earth production were minimal, because much of .
As a source of strategic commodities for high technologies, the deposits of rare earth elements (REEs) in China are a world-class phenomenon. The combination of the world's largest accumulation of REEs in the Bayan Obo deposit and the low cost of mining the extremely valuable heavy REEs from residual deposits makes China almost a monopoly producer. The Bayan Obo mine, located in Inner Mongolia, China, is the largest light rare earth body ever found in the world. The research for rare earth elements (REEs) enrichment in atmospheric particulates caused by mining and ore processing is fairly limited so far. China produces 85% of global supply of the 17 chemically similar elements crucial to smartphone, camera lens and magnet manufacture – and half that output is from the city of Baotou. And although China seems to wield great power over this critical global supply chain, the truth is that the country can’t just bring the West to its knees by limiting exports of rare earth elements.
