摘要:
为探究宜昌磷矿中主要组分的赋存状态和矿物条带的工艺性能以确定其重介质选矿工艺的可行性，对宜昌磷矿进行了工艺矿物学研究.首先使用化学成分分析和荧光成分分析对矿石中各条带的矿物成分和化学成分进行测定，再对矿石中各条带解离性进行测定，并用重液浮沉法对各条带的比重分布进行测试.结果表明，宜昌磷矿石中98.98%的五氧化二磷分布在磷块岩条带中，同时磷块岩条带含有2.29%倍半氧化物，磷块岩条带重量百分比为81.32%；磷块岩条带和脉石条带宽度大且各条带之间存在硬度差别，磷块岩条带易于单体解离；在密度范围2.7～2.9，磷块岩条带与粘土质条带可通过重介质选矿选别.因此宜昌磷矿采用重介质选矿，可先选别出矿石中的磷块岩条带，然后再处理倍半氧化物，可获得合乎要求的优质磷精矿.
Abstract:
To verify feasibility of heavy medium separation of Yichang phosphate, the process mineralogy of Yichang phosphate ores including chemical compositions, occurrence, particle assemblage size and process performance of each band was studied. The mineral composition and chemical composition of each band were tested firstly by chemical composition analysis and fluorescence analysis, then the dissociation of mineral was studied and the proportion of distribution of each band was revolved by heavy liquid method. The results show that phosphorus pentoxide of 98.98% in Yichang phosphate rock is mainly distributed in phosphate rock bands which contain 2.29% sesquioxide and 81.32% weight percentage；phosphate rock band is easy to monomer dissociation because the width of phosphate rock and gangue bands are both long，and there are differences in hardness between each band; the difference of proportion between phosphate rock band and clay belt is so big that clay belt is easily separated by heavy medium separation in the range of 2.7\|2.9. So Yichang phosphate rock should adopt heavy medium separation，grading phosphate rock ore belt and then processing sesquioxide to obtain high quality phosphate concentrate in line with the requirements.
