摘要
介绍了黑石砬子铁矿属沉积变质铁矿床,矿石矿物成分较复杂,通过野外及室内岩矿观察研究,铁矿石呈粒状变晶结构,条带(纹)状构造;有用矿石矿物为磁铁矿、假象赤铁矿;脉石矿物以石英为主,局部含少量碳酸盐矿物(菱铁矿、铁白云石、方解石)、透闪石、绿泥石等,铁矿物镶嵌特征及粒度测试结果显示为易选矿。
Heishilazi iron deposit is a kind of sedimentary metamorphic iron deposit,ore mineral composition is complicated,iron ore is granular metacryst texture and band（barred） structure through the observation and study on rock and ore both in field and indoor;useful mineral ores are magnetite and martite;and gangue mineral is quartz-based with a small amount of carbonate minerals（siderite、 ankerite、 calcite）、 tremolite、 chlorite,etc.,iron minerals mosaic features and particle size test results show is a easy dressing ore.
