据有关资料介绍,我国铁矿石A+B+C+D的储量只有497.36亿吨,其中97.4％属贫矿,能直接入炉的富铁矿只占总储量的2.6％,平均品位仅33％。其中A+B+C的储量有248.04亿吨,真正能开采的约有180亿吨。若按我国钢铁发展规模为1亿吨生铁估算,现有铁矿石资源仅用40多年就枯竭了。
According to relevant information, China’s iron ore A + B + C + D reserves of only 49.736 billion tons, of which 97.4% is a poor mine, can directly into the furnace of iron ore reserves accounted for only 2.6% of the total average grade of only 33 %. Among them, the reserves of A + B + C are 24804 million tons, and the actual recoverable amount is about 18 billion tons. According to China’s iron and steel development scale of 100 million tons of pig iron estimated that the existing iron ore resources in only 40 years to dry up.
