Since 2005, China government established series of regulations to rectify Chinese rare earth industry. Especially, the notice of “ceasing the issue of new mining license and controlling the gross rare earth mining volume” implemented in April of 2006 largely reduced the mining in Southern China. Active downstream market increased the demand for raw materials. For example, rapid development of NdFeB magnets enlarged their demand for Pr, Nd, Tb, Dy metals and their compounds year by year, which correspondingly stimulated the demand for raw materials like neodymia, PrNd oxide, terbia, dysprosium oxide and their metallic products. Under such circumstance, there was significant increasing of the production volume and price of NdFeB permanent magnets related products. After six years depression, prices Since, 2005, China government established series of regulations to rectify Chinese rare earth industry.
