中国查明铁矿资源储量的数量、 分布及保障程度分析

以中国2005年的铁矿资源储量库为基础, 以辽宁、河北、四川、山西、内蒙、北京、安徽、山东、湖北9省(市、区)为重点, 分析总结了我国查明铁矿区、累计查明铁资源储量和铁保有资源储量的数量和分布特点、占有情况及保障程度。结果表明：我国铁矿保有资源储量大, 在数量上是可以保障钢铁工业的需求的；这些保有资源储量中的大多数选矿容易, 开采利用在技术上是可行的；虽然我国铁矿资源总体上属贫矿, 但在当前市场价格如此之高的情况下, 开采利用是经济的。为了缓解目前铁矿石市场供不应求的局面, 减少对外依存度, 建议加大国内矿山开发力度, 提高铁矿石产量, 重点在辽宁鞍山?本溪地区、河北冀东?密云地区、四川西昌?攀枝花地区、安徽宁芜地区扩大采选能力。

Analysis of the Quantity and Distribution of the Total Identified Iron Resources in China and Their Supply Capability

Based on Iron Ore Resources Database of China in 2005, this paper sums up the number and distribution of iron deposits, the quantity and distribution of the total identified iron resources and the retained iron resources, the classification of the retained iron resources, and the supply capability of the iron resources in China. Some conclusions have been reached: there are sufficient quantities of retained iron resources for feeding the iron and steel industry in China; most of the iron ores are easy to concentrate; although iron contents are totally low in most ores, the utilization of these ores remains worthwhile and economical under current high iron prices. In order to ease the situation that demand exceeds supply in current iron ore market and reduce the dependence on imported iron ore, the authors suggest that the domestic mines should be further exploited for increasing their iron ore out-put, and further mining capability should be disposed in Anshan-Benxi area of Liaoning Province, Jidong area in Hebei Province, Panxi area in Sichuan Province, and Ningwu area in Anhui Province.
