铁矿石中碳酸铁测定的方法有很多种,本文利用三氯化铝浸取法〔1〕,通过溶液的酸效应使其在低酸度下选择性浸取分离碳酸铁,并将菱铁矿的铁定量地浸取出来而其它共存矿物基本不被浸取的方法进行测定,并对其测定条件的影响因素进行分别试验与分析比对,对测定结果及其相应影响因素进行了讨论与分析。
There are many methods for the determination of iron carbonate in the determination of iron carbonate, aluminum chloride leaching method [1], the acid effect of the solution to make it at a low acidity selective leaching of iron carbonate, and siderite Iron was quantitatively leached out while other coexisting minerals were not substantially leached. The influencing factors of the determination conditions were separately tested and compared with each other, and the results and the corresponding influencing factors were discussed and analyzed.
