At present, rare earth ore mined in China and other countries in the world, the content of rare earth oxides is only a few percent, or even lower. In order to meet the production requirements of smelting, the ore minerals and gangue minerals will be processed before smelting. and other useful minerals apart to increase the content of rare earth oxide, a rare earth to meet the obtained rare earth ore metallurgical requirements. The beneficiation of rare earth ore is generally carried out by flotation, and is often supplemented by re-election and magnetic separation to form a variety of combinations of beneficiation processes. The rare earth deposit of the Baiyun Obo mine in Inner Mongolia is a carbonate rock deposit of iron dolomite. It is associated with rare earth minerals in the main component iron ore (in addition to fluorocarbon antimony ore, monazite, there are also several kinds of antimony and rare earth minerals). The produced ore contains about 30% iron and about 5% rare earth oxide. First in the mine After the large ore is broken, it is transported by train to the concentrating plant of Baotou Iron and Steel Group Co., Ltd. The task of the concentrator is to increase the Fe2O3 from 33% to more than 55%. First, grind and classify on a conical ball mill, and then use a cylindrical magnetic separator to select a primary iron concentrate of 62 to 65% Fe2O3. The tailings continue to undergo flotation and magnetic separation to obtain a secondary iron concentrate containing 45% Fe2O3 or more. The rare earth is enriched in the flotation foam and the grade is 10-15%. The enrichment can be selected from a coarse concentrate having a REO content of 30% by a shaker, and after reprocessing by the ore dressing equipment, a rare earth concentrate having a REO of more than 60% can be obtained.

Shanghai baosteel import mill alone provides more than 30 replace imported
Roller Bearing , using performance got the user's high praise, be included in
"baosteel spare parts jointly developed supply center member". These
replace the imported bearing not only has the good economic efficiency, there
is a wide range of social benefits.
Xibei Bearing pay attention on technical
transformation, constantly introduce domestic and foreign advanced equipment
and testing instruments; attaches great importance to quality management, and
constantly improve product quality and grades. NXZ product not only replace
imported rolling mill bearing for many domestic steel plant, but also as OEM for
the TIMKEN in accordance with standard which higher than international with four
row Tapered Roller Bearing for rolling mill. Xibei Bearing was brought into its
global procurement plan, exportIndiaandEuropeand other regions.
In the process of
development of form a complete set of metallurgical rolling mill bearings, the
company continuously according to user's working conditions of the host and
special requirements for personalized design and manufacturing, to meet user
