由于我国矿山资源缺乏,生产困难,影响降低成本的不利因素很多,2000年国产铁矿石产量不会有大幅度增产,基本将维持在2.3～2.4亿t的水平。　　近年来我国钢铁产量逐年增长,而我国铁矿石产量却徘徊不前,呈下降趋势。从而使我国铁矿石的自给率逐年下降,80年代初自给率达89%,至... Due to the lack of mining resources in our country, difficulties in production and many unfavorable factors affecting the cost reduction, there will be no substantial increase in output of domestic iron ore in 2000, basically maintaining the level of 2.3 to 240 million tons. In recent years, China’s steel output has increased year by year, while China’s iron ore output has stagnated, showing a downward trend. So that the self-sufficiency rate of iron ore in our country declines year by year, and the self-sufficiency rate in the early 1980s is 89%.
