摘要
For developing the rutile ore in Nanzhao-Biyang rutile ore belt as soon as possible, the authors 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 the 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.
