我国是世界上铁矿资源比较丰富的国家之一,铁矿总储量仅次于苏联(111.4亿吨)、巴西(800亿吨),居第三位;从铁金属量来算,列澳大利亚之后,居第四位.我国有十个省(区)铁矿储量在10亿吨以上,占全国总储量的80%.东北、华北两大区的探明储量占全国一半,西南区占五分之一,这三大区钢铁工业比较发达,资源利用率较高.西北地区因地质工作程度较低,大部分地区未开展工作,故目前储量较少,从成矿地质条件分析,还是有相当远景的.我国铁矿的特点是贫矿多、富矿少.按保有储量计算,品位大于50%的富矿仅占总储量的6%;可以直接人炉的平、高炉富矿更少.
China is one of the countries with rich iron ore resources in the world. The total reserves of iron ore are second only to the Soviet Union (11.14 billion tons) and Brazil (80 billion tons), ranking third; from the amount of iron metal, after Australia , ranking fourth. China has ten provinces (regions) of iron ore reserves of more than 1 billion tons, accounting for 80% of the country’s total reserves. Northeast and North China’s proven reserves accounted for half of the country’s total, five points in the southwest One of the three major regions, the steel industry is relatively developed, and the resource utilization rate is relatively high. Because of the low level of geological work in the northwestern region, most of the regions have not carried out work, so the current reserves are less, and from the analysis of metallogenic geological conditions, there is still considerable Prospects. China’s iron ore is characterized by a large number of lean ore deposits and low ore deposits. According to calculated reserves, rich deposits with a grade greater than 50% only account for 6% of the total reserves;
