为了满足经济发展的需求,进入新世纪之后我国粗钢产量呈现出高速增长态势,由此带来对钢铁生产原料需求的增加,但同时因我国铁矿石资源有限、品位较低和杂质较多,且开采难度较大,不能满足国内钢铁生产需求,因而每年需要大量进口铁矿石,数年来依存度持续在60%以上。 In order to meet the demand of economic development, after entering the new century, the output of crude steel in our country shows a rapid growth trend, which will bring about an increase in the demand for raw materials for steel production. However, due to the limited resources, low grade and more impurities in China’s iron ore resources, , And difficult to mine, can not meet the domestic steel production demand, which requires a large number of imported iron ore each year, the degree of dependence over the years continued in more than 60%.
