| 摘 要： | 应用化学组分分析、X射线衍射分析、扫描电子显微镜及X射线能谱法等多种方法对贵州省瓮福地区磷尾矿中钙、镁及磷的赋存状态作了分析和研究。结果表明:①选自该矿区的磷尾矿为高镁(wMgO17.26%～17.65%),高钙(wCaO34.11%～34.56%),低磷(wP2O55.30%～5.69%)的固体矿物;②尾矿中镁主要以白云石形式存在,并有少量以磷酸盐和硅酸盐形式存在;钙主要也以白云石形式存在,加上少量以方解石和磷酸盐形式存在;磷主要以磷灰石形式存在,有少量存在于铁氧化物及独居石、磷钇矿中。

| Abstract: | Naturally endowed states of calcium,magnesium and phosphorus in phosphorite tailings sampled from Wengfu district of Guizhou province were studied and analyzed by chemical analysis,X-ray diffraction analysis,scanning electron microscopy and X-ray photoelectron spectrometry.It was found that: ① the phosphorite tailings sampled from the ore slag were solid minerals containing high magnesium(wMgO 17.26%-17.65%),high calcium(wCaO 34.11%-34.56%) and low phosphorus(wP2O5 5.30%-5.69%).② Magnesium in the tailings was mainly present in form of dolomite with small amounts present as phosphate and silicate;calcium was also present mainly as dolomite with small amounts present as calcite and phosphate;phosphorus was present mainly as apatite with small amounts occurred in iron oxide,monazite and xenotime. |
