据业内人士分析认为,国内铁矿石供给不足的问题日显突出,我国钢铁生产所需铁矿石的来源构成将逐步由自产为主变为以进口为主、自产为辅。资料显示,截止目前国内铁矿石探明储量约486亿t,但可开采储量不足180亿t,平均铁品位不到30%。以1997年产铁矿石原矿2.56亿t,耗费铁矿储量约5 According to industry insiders’ analysis, the problem of insufficient supply of domestic iron ore is increasingly prominent. The source composition of iron ore needed for steel production in China will gradually shift from self-produced production to import-based production and self-production assistance. According to statistics, the proven reserves of domestic iron ore are about 48.6 billion tons, but the recoverable reserves are less than 18 billion tons, and the average iron grade is less than 30%. In 1997, 256 million tons of iron ore ore was produced, which consumed about 5 iron ore reserves.
