本文所述的硅灰石的物相分析方法,是作者根据辽北硅灰石对其含矿成份,采用稀盐酸定量提取硅灰石、方解石和白云石的。透辉石则不溶于稀盐酸。在提取分离矿物的基础上,测定酸溶物中的钙、镁、铁、铝和碱溶物中的镁、铁、铅含量,配合测定二氧化碳,即可通过计算求得硅灰石、方解石、白云石、透辉石、钙铁榴石、钙铝榴石六种矿物的含量。 The wollastonite phase analysis method described in this paper is based on the wollastonite Liaoning Province for its ore-bearing ingredients, the use of dilute hydrochloric acid quantitative extraction of wollastonite, calcite and dolomite. Diopside is insoluble in dilute hydrochloric acid. Calcium, magnesium, iron, aluminum and alkali soluble substances in the acid solution are measured on the basis of the extraction of the separated minerals, and the content of magnesium, iron and lead in the acid solution is determined. With the determination of the carbon dioxide, the wollastonite, calcite, Dolomite, diopside, dulcite, gypsum six minerals content.
