The Qian an area is rich in iron ore resources, which known as the the iron Qian an said.Since the second half of 2003, due to the sudden seven up iron ore prices, the original no exploitation of the economic value of the corner to chicken coop mine grade 10% to 15% of the ultra-poor iron ore, as well as deep buried, stripping production ratio is more than 20 iron ore, iron ore concentrate mined value price. The Qian an territory of proven iron ore reserves is 2.56 billion tons rough statistics Qian an territory recoverable reserves of 225 billion tons. Since its the Qian an place in 1984 began construction of the mine, the existing ore dressing plant is more than 500, more than 500 million tons of the total annual iron ore processing, iron mill scale to 100 million Ua, belonging to small and medium-sized iron concentrator, a lot of mixed ore processing doped with a grade of less than 20% of the ultra-poor magnetite ore concentrator. As easy to wear and easy election, few impurities, thus various technical and economic indicators are good, very significant economic benefits. Richard Parsons addresses the importance of the matter here. The crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound.

Jaw crusher (jaw crusher), having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio, cubic particles advantages of material was broken; PF-II series impact crusher machine, suitable for crushing hard materials, such as cement crusher, with a production capacity of the material advantages of small particle size. Baogang Group Company is very concerned about the development and utilization of poor iron and depleted iron ore. In 2006, concentrator of the Inner Mongolia region orebody self transformation. When selected ore grade MFe 13.00% l4 00%, after primary dry-type process, the rougher concentrate grade is 20.00% to 21.00%. Two sections of the stage mill grinding, fine sieve screening machine three weak magnetic separation process, the grinding fineness – 0 074 mm accounted for 70% elected iron concentrate grade of 63.00%, the production rate is 10%. beneficiation than 10 metal recoveries of 45% to 50%.
