用10%的盐酸,在室温24小时内能使碳酸盐矿物从非碳酸盐矿物中分离出来。在这种情况下,粘土矿物和黄铁矿几乎全不溶解。然而,适宜于碳酸盐矿物溶解的条件石膏也能溶解。菱铁矿在研究的所有九个碳酸盐矿物中最难溶解。为此,在这里推荐一个容易再现的鉴定不溶残渣的方法。 With 10% hydrochloric acid, carbonate minerals can be separated from non-carbonate minerals within 24 hours at room temperature. In this case, clay minerals and pyrite are almost completely insoluble. However, gypsum, which is suitable for dissolution of carbonate minerals, can also dissolve. Siderite is the most difficult to dissolve in all nine carbonate minerals studied. For this reason, an easily reproducible method of identifying insoluble residue is recommended here.
