| 摘 要： | 中国铁矿成矿地质条件有利,铁矿床类型齐全,以沉积变质型、岩浆型铁矿成矿潜力最大,但品位较低;矽卡岩型和火山岩型铁矿规模较小,但富矿较多;沉积型铁矿多为难选冶的铁矿,风化淋滤型铁矿的成矿潜力很小。全国已查明的铁矿资源储量丰富,多属易选铁矿石类型,多分布于东部铁矿生产基地及其附近,如果铁矿石50%立足国内供应,则基础储量可以保障供应超过10年,还有大量资源量可以转化为基础储量,延长保障年限。中国还有大量铁矿点、矿化点有待进一步评价,有大量磁异常有待查证,已知铁矿区的深边部近年来找矿不断取得突破,西部地区铁矿进一步找矿的潜力巨大,具有立足国内长期保障铁矿资源供应的潜力。

| Abstract: | The geological condition in China is favorable for iron mineralization. There are six types of iron deposits in China: sedimentary-metamorphic type, magmatic type, skarn type, volcanic type, sedimentary type and weathering-leaching type. Among which the first two types have the greatest potential, while the grade generally is low. The size of the skarn type and volcanic type generally is small, but most rich iron deposits in China come from these two types. Most of the ores from sedimentary type are difficult for beneficiation. The metallogenetic potential of weathering-leaching type is very small. Identified iron resource in China is abundant ane most of them are suitable for beneficiation. Majority of these identified iron resources distribute in or near the traditional iron production bases in eastern China. The basic reserve of the identified iron resource can meet up to 50% of domestic demand for more than 10 years. Additionally, identified resource can be further upgraded into basic reserve and provide longer supply. There also exist many mineral occurrences and prospects pending on further evaluation as well as many magnetic anomalies to be inspected. There have been ore-prospecting breakthroughs in or around the deep and lateral parts of identified iron deposits in recent years, also there is large potential of discovering new iron deposits in western China, which provide positive vision for ensuring long-term iron demand mainly by domestic resources. |
