In recent years , with the rapid development of national economy, the steel industry surge in demand for iron ore , iron ore development of various types of capital to unprecedented enthusiasm , a large number of iron ore mining projects have been put into operation by the end of 2008, China has formed nearly 900 million tons / year of ore production capacity , with production capacity of about 5,000 tons. In the new capacity mines , Hebei Iron and Steel Group has 377 million tons, 2.26 million tons of TISCO , Baotou Barun Mining 6 million tons , 3.83 million tons Angang , Maanshan 100 million tons, 600,000 tons WISCO , Beijing Shouyun 250,000 tons , 940,000 tons of Tangshan Shougang Malanzhuang , Tong Gang Huadian mining 550,000 tons , 500,000 tons of iron ore in Xuzhou , Laiwu Lunan Mining 900,000 tons , 600,000 tons Daxigou Shaanxi , NANJIANG mining 270,000 tons , Han Xing metallurgical Mining Authority, 250,000 tons , 220,000 tons Lu in the metallurgical and mining .
In recent years, China's iron ore production in substantial growth in recent years , according to statistics , in 2003 production of 261.46 million tons of ore , to 2008 has grown to 824.01 million tons , is 3.15 times the annual output of 2003 , an average annual increase of 25.8 %. Affected by the financial crisis in 2009, China 's iron ore production growth rate decreased, but the annual output reached 880 million tons , an increase of 6.8 % over the previous year . Lower ore grade , the average grade was selected less than 30 %. Among them, 70% open-pit mining , underground mining accounted for 30 %. The 2009 domestic demand for iron ore market is as high as 1.817 billion tons , the gap in part by imports. Then imported a total of 627 million tons of iron ore -rich , an increase of 41.6 % over the previous year , accounting for 69 % of domestic market demand for iron ore .
Currently , there are 2251 District untapped iron ore , accounting for 61.89% of the national total proven iron ore zone ; unused reserves of up to 41.047 billion tons of iron ore , accounting for 63.54% of proven iron ore reserves in the country to maintain the . 62% of 64% of the proven proven mining reserves of unused resources , more complex reasons , some because of poor traffic conditions , either because metallurgical technology did not pass , either because a large burial depth , some because of lower grade , either because groundwater is too large.
In recent years, with the continuous improvement of the country 's infrastructure , especially the substantial increase in iron ore prices , unused mine has proven a lot of internal and external construction conditions initially have . In 2251 the mine has not been developed , and has been included in the 1015 plan can use mine , accounting for 45.09% of the national total undeveloped iron ore region , with reserves of 20.945 billion tons of iron ore , accounting for the country to maintain the proven iron ore 32.42% stone resource reserves. Among them, there can be planned use of mines in Sichuan 35 , proved reserves 6.308 billion tons ; Hebei have to plan the use of mines 52 , proved reserves 2.488 billion tons ; Inner Mongolia has to plan the use of mines 218 , proved reserves 21.45 million tons; Liaoning has to plan the use of mines 59 , has identified reserves of 2.062 billion tons of resources ; Shandong has to plan the use of mines 104 , proved reserves 1.771 billion tons ; Anhui have to use mine 50 plan , identification of resources reserves of 1.517 billion tons ; Shanxi have to plan the use of mines 56 , proved reserves 1.429 billion tons . Resources in these seven provinces (regions ) may be planning a total of 574 mines use , proved reserves 17.72 billion tons , accounting for planning the use of resources available reserves of 84.6% .
Be included in temporarily difficult to use mine has 1236 , accounting for 34 % of the total area of proven iron ore , iron ore reserves of up to 20.1 billion tons . Included in temporarily difficult to use mine that these mines currently does not have the scale to develop internal and external conditions , such as traffic conditions and some very poor , some metallurgical technology yet to cross the border , some of the devastating effects of groundwater exploitation problem has not yet completely resolved.
Useful minerals in the past due to fine particle size ore refractory and difficult to develop long-term and become stay mine. Zhengzhou General Mining Machinery Co., Ltd. and a number of iron ore plant specialists through communication, using efficient crushing + roughing processing technology to solve the problem of dressing , so in the absence of iron ore into the mill , on the first particles by crushing the ore crushing machine to 5 mm or less , rough first direct election , the non-iron ore filtered out to improve the taste of ore , for many poor mining to solve technical problems.
Iron ore has been developed using mainly distributed in Liaoning, Hebei, Anhui , Sichuan, Yunnan , Shanxi, Inner Mongolia, Shandong, Gansu and Hubei provinces , has formed Anshan - Benxi , Xichang - Panzhihua , Jidong - Miyun , five Taiwan - Lan County , Baotou - Bayan Obo , eastern Hubei , Ning Wu , Jiuquan , Hainan Shilu , Handan - Xingtai , Chengde and a number of iron ore production base.
Booming iron ore zones, mining and processing equipment business offers opportunities , many mining machinery manufacturing enterprises have carried out technical upgrades, equipment improvements, as is the ability to occupy a place in the present and future market competition
