稀土是化学性质相似而又比较难分离的17个元素的总称,自1794年发现第一个稀土元素-钇以来已有近200年的历史。我国开展对稀土的研究和应用始于50年代末,当时的北京有色金属研究院试制了我国第一批单一稀土氧化物.我省也于50年代末在查定钨矿的过程中发现了稀土矿床,并于1965年由西华山钨矿生产了首批磷钇矿稀土精矿,从而开创了我省稀土工业的历史. 一、稀土是特种“维生素” 稀土元素由于其性质特殊,因而应用范围越来越广,几乎已成为各行各业不可缺少的一种特殊的“维生素”。在农业、林业、牧业、养殖业上稀土可作微肥或者添
Rare earth is a general term for the 17 elements that are similar in chemistry but difficult to separate. It has been nearly 200 years since the first rare earth element, yttrium, was discovered in 1794. The research and application of rare earth in our country started in the late 1950s when Beijing Nonferrous Metal Research Institute trial-produced the first batch of rare earth oxides in our country and the province found rare earth Deposit and produced the first xenotime ore rare earth concentrate from Xihuashan tungsten mine in 1965, thus creating a history of rare earth industry in our province. (1) Rare earth is a special “vitamins” rare earth element Because of its special nature, the scope of application More and more widely, almost all walks of life have become indispensable a special kind of “vitamin.” In agriculture, forestry, animal husbandry, aquaculture rare earth can be used as fertilizer or Tim
