前言:近几年我国钢铁工业快速发展,钢铁产能急剧扩张,产量由2003年的2.2亿吨增加到2008年的5亿吨,对铁矿石的需求也相应急剧上升。我国铁矿石原矿产量大幅增加,但由于品位较低,近一半的铁矿石需求还需要进口来弥补,进口铁矿石价格逐年上 Foreword: In recent years, with the rapid development of China’s steel industry and the rapid expansion of its steel production capacity, its output has increased from 220 million tons in 2003 to 500 million tons in 2008, and the demand for iron ore has also risen sharply accordingly.
