摘要:
全球铁矿资源非常丰富,但分布极不均衡,澳大利亚、俄罗斯、巴西三国铁矿资源储量合计占全球储量近60%,中国铁矿资源储量全球排名第四,占到全球的8.47%,与国外相比,中国铁矿平均入选品位约为25.54%,整体上低于国外平均入选品位,但选矿平均回收率达到76.09%,与国际相比,铁矿资源综合利用水平较高。过去百年全球铁矿石产量持续上升,供大于求,预计未来短时间内供应持续的过剩的局面将会持续,铁矿石价格将持续疲软。

Abstract:
The global iron ore resources are abundant , but the distribution is uneven .About 60%of global iron ore resources come from Australia , Russia and Brazil .In the past century , the production of iron ore has been increasing , which makes iron ore over supply .This situation would last for a pe-riod, and the price iron ore would continuously decrease .The average iron grade is 25.54%in Chi-na , which is lower than foreign average grade .The average iron recovery in China , however , is up to 76.09%, which is slightly higher than foreigh average recovery .In this paper , the status quo of global iron ore resource and application is comprehensively introduced , and the supply and demand as well as price changes are analyzed in detail .Furthermore , this study provides reasonable refer-ences for investment , exploitation and management .of iron ore industry in China .
