摘要
在传统的铁矿石物相分析中,磁性铁用盐酸溶解,有的样品溶解不完全,故而造成各单项加和低于全铁分析结果。笔者通过试验,发现用硫磷混酸或残渣碱熔能很好地分解磁性铁,使单项加和与全铁分析结果一致。
The traditional phase analysis for iron ore uses HCl for dissolving magnetic iron which makes some samples incomplete solution,causing analytical error.The authors use sulfuric acid-phosphoric acid mixture or alkali for melting residue and have achieved very good results,eliminating the analytical error.
