海泡石矿物定量分析通常采用X射线衍射法、红外光谱法。但用化学物相分析进行海泡石矿物定量,至今未见国内外文献报导,本文探索了应用选择性溶解方法进行海泡石矿物化学物相定量分析的可能性。以江西乐平海泡石粘土矿床为对象,研究了粘土层中各种伴生矿物在选择性溶解时 Quantitative sepiolite mineral analysis usually uses X-ray diffraction, infrared spectroscopy. However, the quantitative analysis of sepiolite minerals by chemical phase analysis has not been reported in the literature at home and abroad, this paper explores the possibility of quantitative analysis of sepiolite mineral chemical phases using selective dissolution method. Taking Leping sepiolite clay deposit in Jiangxi Province as an example, the effects of various associated minerals in the clay layer on selective dissolution
