Mineral form
1、As the basic constituent elements of minerals, rare earths are endowed in the form of ionic compounds in the mineral lattice, constituting the indispensable components of minerals, such as monazite;
2、As the impurity element of minerals, it is dispersed in rock-forming minerals and rare metal minerals in the form of isomorphic substitution, such as apatite;
3, as an ionic state is adsorbed on the surface of certain minerals or between particles, such as mica.
Rare earth mineral resources distribution
1, the distribution of reserves is highly concentrated. So far, more than two-thirds of the country has been found in more than one-third of the provinces and districts of the thousands of deposits, sites and mineralisation origin, in addition to Inner Mongolia's Baiyun Ebo, Jiangxi Gannan, Guangdong Guangdong Yuebei, Sichuan Liangshan for the centralised distribution of rare earth resources, Shandong, Hunan, Guangxi, Yunnan, Guizhou, Fujian, Zhejiang, Hubei, Henan, Shanxi, Liaoning, Shaanxi, Xinjiang and other provinces and districts are also found in the rare earth deposits, but the amount of resources than the Mineralisation concentrated rich area is much less.
2. Light in the north and heavy in the south. Ninety-eight per cent of the country's total rare earth resources are distributed in Inner Mongolia, Jiangxi, Guangdong, Sichuan, Shandong and other areas, forming a distribution pattern of north, south, east and west, with the distribution characteristics of light in the north and heavy in the south.
3, mineral resources reserves, variety. Now the proven reserves of rare earths amount to more than 100 million tonnes, and there is a greater potential for resources, the full range of varieties.
Rare earth ore application prospects
1, in the metallurgical industry: rare earth metals or fluoride, silicides added to steel, can play a role in refining, desulfurisation, neutralisation and low melting point of harmful impurities.
2, in petrochemical industry: molecular sieve catalysts made of rare earths have the advantages of high activity, good selectivity and strong resistance to heavy metal poisoning.
3, in glass ceramics: can be widely used as polishing powder for optical glass, spectacle lenses, picture tubes, oscilloscope tubes, flat glass, plastics and metal tableware polishing and so on.
4, in new materials: with high remanent magnetism, high coercivity and high magnetic energy product, it is widely used in electronic and aerospace industries.
Beneficiation process
Due to the different metal element contents of rare earth ores around the world, so according to the different physical and chemical properties of rare earth minerals and associated veins and other minerals, the beneficiation of rare earth ores usually adopts the following methods: radiation beneficiation, gravity beneficiation, magnetic separation, flotation, electrowinning, etc., and the users can choose the equipment and beneficiation process according to their own actual situation.
