摘要
建始官店铁矿床是宁乡式铁矿中最大的一个矿床,由于含磷较高,选冶困难,一直未大规模地开发利用。通过对建始官店矿石中铁矿物、胶磷矿及脉石矿物的种类、含量、嵌布特征、物理化学性质的研究,查明了铁矿石中主要含铁矿物及有害元素磷的赋存状态。研究了建始官店铁矿石中有用组份的工艺矿物学等特征,对铁矿石进行重选、强磁选、浮选等方法的选矿效果和可能存在的问题作分析,为铁矿石开发利用及研究提供借鉴,为选矿试验奠定良好的基础。
Guandian iron ore is the largest Ningxiang style iron ore body in China. The iron ore is rich in phosphorus and hard to benefieiate and smelt, so for a long time the iron ore didna be exploited and utilized in a large scale. Based on the research of the type, content ,occurrence and physicochemical properties, the major iron-bearing miner- als and the occurrence of phosphorus were identified. According to the research of the technological mineralogy characteristics of Guandian iron ore, the effects and problems possibly appearing in the methods of gravity separa- tion, high-intensity magnetic flotation and flotation were expected, providing reference and lay a good foundation for the iron ore beneficiation and smelting.
