China has rich rare-earth mineral resources, ore favorable conditions, called unique, proven reserves in the world, for the development of China rare earth industry to provide a solid foundation.

Rare Earth has been widely used in electronics, petrochemical, metallurgy, machinery, energy, light industry, environmental protection, agriculture and other fields. Application of rare earth produce fluorescent materials, rare earth metal hydride battery materials, electric light materials, magnetic materials, hydrogen storage materials, catalytic materials, ceramic materials, laser materials, superconducting materials, magnetostrictive materials, magnetic refrigeration materials, magneto-optical storage materials, optical fiber materials.

Is the use of rare earth ore mineral composition of ore between the various physical and chemical nature of the differences with different dressing methods, with different mineral processing, different processing equipment, the useful minerals in the ore enrichment up to remove harmful impurities, and gangue minerals and make the mechanical separation process.

At present, China and the rest of the world rare earth ore mined, only a few percent of rare earth oxide content, and even some lower, in order to meet the requirements of smelting production in the former by smelting ore, rare earth minerals and gangue minerals and other useful minerals separately, in order to improve the content of rare earth oxides, rare earth get to meet the metallurgical requirements of the rare earth concentrate. Rare-earth mineral ore flotation method generally used, and often supplemented by re-election, composed of various combinations of magnetic beneficiation process.cooling machine: http://www.china-hxjq.com/n273.html

Bayan Obo rare earth ore mine in Inner Mongolia, is ankerite carbonatite type deposits, the main component of iron ore in the accompanying rare-earth minerals (except Bastnaesite, monazite, there are several kinds of niobium, rare earth minerals). Iron ore mined in about 30%, 5% rare earth oxides. Broken ore in the mine after the first large, transported by train to Baotou Iron and Steel Group Corporation concentrator. Concentrator mission is to Fe2O3 from 33% to 55%, first grade conical ball mill grinding on, and then drum magnetic separator selected and 62 ~ 65% Fe2O3 an iron ore concentrate. The flotation and magnetic separation tailings continue to get more than 45% Fe2O3 with secondary iron ore. REE enrichment in the froth, the grade of 10 to 15%. The enrichment can be selected shaker REO content of 30% crude concentrate, and then processed by the processing equipment, available REO60% or more of the rare earth concentrate.

Rare-earth ore crushing, ore dressing, grinding the purpose and mission is to make a useful mineral ores in sufficient monomer dissociation and size requirements for sorting and crushing as much as possible light, even granularity. Henan Hongxing Industries for crushing, grinding mill, processing of rare earth minerals. Henan Hongxing Raymond mill, three-ring mill, powder mill, jaw crusher, impact crusher, as well as mineral equipment, ball mill, dryer, etc. can be further used for the rare earth resources play a positive role. Raymond Mill which sold foreign grinding mill, cement and other industries, mineral resources in the field of deep processing of rare earth show a distinctive advantage.
