摘　　要：用显微镜研究了灵山煤泥的黄铁矿赋存显微特征,提出了一种比较精确计算煤泥中不同赋存形态黄铁矿含量的统计方法。结果表明,煤泥中黄铁矿的存在形态是多样的,可分为单体解离、镶嵌、充填于植物胞腔3种。并结合统计结果分析了黄铁矿的种类、粒度及赋存形态等对煤泥可选性的影响。The paper studied the micro characteristics of pyrite distributed in Lingshan slime with microscope The paper provided a statistic method to accurately calculate the pyrite contents distributed in the slime The study results showed that the distribution characteristics of the pyrite in the slime are different and could be divided into three types: monomer, incrustation and filling in plant cell With the statistic results, the paper analyzed the type, size and distribution of pyrite influenced to the washability of pyrite 
