| 摘 要： | 为了开发利用南召—泌阳金红石矿带的金红石,综合分析了以往资料,并在实地踏勘、样品测试和重点地段综合研究基础上,查明了各矿段金红石矿基本地质特征、金红石赋存状态、嵌布特征、粒度变化特征、金红石富矿体的主要赋存位置。区内粗粒易选富矿体位于矿带中段的左老庄组一段上部（北部）。采用以微生物提纯金红石粗精矿为标志的新工艺,取得了良好的选矿试验效果。刘岗矿区的1号和2号富矿体可作为进一步研究和开发利用的重点。

| Abstract: | For developing the rutile ore in Nanzhao-Biyang rutile ore belt as soon as possible,we have sorted the previous data,made field reconnaissance,tested samples and comprehensively studied key ore blocks.The basic geological features of the blocks,occurrence pattern（mosaic and grain size variation） of rutile,location of rich rutile ore bodies are made clear.The coarse-grained and easy beneficiated rich rutile orebodies are at the upper part of the Zuolaozhuang Formation（North） in middle of the ore belt.adopting new microbial technology shows good result of rough concentrates.Rich rutile ore body I and II in Liu Gang block can be regarded as the focus for further research and development. |
