摘　　要：以最新全国储量数据库为基础,分析总结我国查明低品位铁矿资源储量的数量、分布特点、类型、矿床规模及矿石可选性等。结果表明:我国查明低品位铁矿资源储量约184亿吨,约占全部铁矿石资源量的30%。主要分布在河北省、辽宁省、山西省等近17个省(区)。主要矿床类型有沉积变质型、沉积型、接触交代-热液型等。小型矿多,大型矿少。大型低品位铁矿区仅占查明数的1.08%,而储量却占我国低品位铁矿查明资源储量的62.37%。我国查明低品位铁矿石基本可选,部分易选,难选矿石仅占2.17%。Based on new Mineral Resources Database of China, this paper sums up the number, distribution, type, size and optional of identified low-grade iron resources in China. The results shows that the identification low-grade iron resourcereserves in China is about 18.4 billion tons,accounting for about 30 percent of iron ore resources, which is mainly distributed in Hebei, Liaoning, Shanxi and other 17 provinces （area）. Low-grade iron deposits in China are classified into metamorphosed sedimentary type iron deposits, sedimentary type iron deposits, contact metasomatic-hydrothermal type iron deposits and others. Small ores are more, and large ores are less. Large low- grade iron regions account for only 1.08% of identified number, but the reserves account for 62.37% of the total re- serves. The identified low-grade iron resources in China basically can separate, some is easy, and refractory ore ac- counts for only 2.17%.
