硅灰石的分析已有人作过这方面的工作。在生产中我们发现,用选择性溶剂提取分离矿物的某些条件(如酸度、温度、时间等)不易控制而使分析结果的重观性欠佳,同时,在计算矿组物分含量时如果选择的元素组分不当也会带来较大的误差。本文针对辽北地区硅灰石矿中硅灰石的共生矿物比较简单的特点,用稀盐酸一次提取硅灰石及共生矿物,用准确度高的分析方法测定MgO、Fe_2O_3、Al_2 O_3等组分,通过测定灼烧减量(LOS)来测定碳酸盐总量,经计算
Wollastonite analysis has been made in this area. In production, we found that some conditions (such as acidity, temperature, time and so on) of extracting and separating minerals by selective solvent are not easy to control and make the analysis of the reworking poor. At the same time, Improper selection of the components of the element can lead to large errors. In this paper, wollastonite wollastonite in Liaoning area is relatively simple symbiotic mineral characteristics, with a single extraction of wollastonite wolframite and symbiotic minerals, with high accuracy analytical method for the determination of MgO, Fe 2 O 3, Al 2 O 3 and other components , By measuring the loss on ignition (LOS) to determine the total amount of carbonate, calculated
