摘要
宁乡式铁矿在湘西北主要分布在三个层位,存在两类矿石结构,这两类矿石结构的铁矿是由不同的成矿方式形成,因而矿石质量也是不同的,具体表现在两类矿石中P、SiO2的含量存在明显差异。通过分析对比,Fe0、Fe22层砾状、豆状类赤铁矿的质量优于鲕状赤铁矿,其中位于二户溪至西界地区的FeO层砾状、豆状赤铁矿矿石质量全区最佳,应为该区的赤铁矿下一步工作的主要方向。
The Ningxiang-type iron ore of the northwest of Hunan province mainly distributed in the three layers,and existed two types of ore-structure.This two types iron ore were formed by different way,so had different ore-quality.This two types iron ore had different P,SiO2 content.We found that the ore-quality of the Fe0 and the Fe2 2 layer＇s gravel-shape and pisiform hematite had an advantage of the oolite-hematite.And the best quality of Fe0-layer＇s gravel-shape and pisiform hematite were in Erhuxi to Xijie area.This area should be the main directions for further work.
