Tombarthite
The global scope, the rare earth reserves the world first, accounting for 40% of the global rare earth reserves, Russia's second accounted for 30%, China's third accounted for 18%, India fourth accounted for 7%.
China is the world rare earth resources is one of the major national, has proved the rare earth resource of about 65.88 million tons. China rare earth resources not only abundant reserves, but also has the mineral resources and rare earth element is complete, rare earth grade and reasonable distribution of mineral occurrence advantages, for China's rare earth industry's development has laid a solid foundation. China rare earth resources metallogenic conditions is very favorable, deposit type single, FenBuMian wide and relatively concentrated.
characteristic: 1.One is the lack of sulfide and sulfate (only extremely individual), it shows that the rare earth elements have a close oxygen sex;
2. The second is rare earth silicate mainly is the island, no lamellar, frame shape and chain structure;
3. The third is part of the rare earth mineral (especially complex oxide and silicate) present amorphous state;
4.The fourth is rare earth mineral distribution, in the magmatic rock and pegmatite in silicate and oxide is given priority to, in the hydrothermal deposit and weathering crust deposit in fluorine carbonate, phosphate is given priority to. Yttrium rich mineral mostly occurs in granitoid and its associated pegmatite, pneumatolytic hydrothermal deposit and hydrothermal deposit;
5.Five is rare earth elements because of its atomic structure, chemical and crystal chemistry close but often symbiosis in the same mineral, namely family of cerium rare earth and rare earth element yttrium family often, there exist a mineral, but this kind of element is not equivalent coexistence, some mineral with containing rare earth cerium family is given priority to, some mineral criterion with yttrium family is given priority to.
