本文提出测定硅灰石化学物相分析的可靠方法。以2％三氯化铝溶液为方解石的选择性溶剂,使与硅灰石分离,此时方解石完全溶解,而硅灰石几乎不溶;以2mol/L盐酸浸取使硅灰石溶解,而在残渣中测定钙铁石榴子石和透辉石。方法用于硅灰石矿分析,获满意结果;矿样加硅灰石单矿物的回收试验结果亦满意。
This paper presents a reliable method for the determination of wollastonite chemical phase analysis. With 2% aluminum trichloride solution as a selective solvent of calcite, and wollastonite separation, calcite completely dissolved at this time, and wollastonite almost insoluble; 2mol / L hydrochloric acid to wollastonite dissolution, and in the Residue determination of calcium iron garnet and diopside. The method was applied to the analysis of wollastonite and satisfactory results were obtained. The recovery results of the mineral wollastonite single mineral were also satisfactory.
