Assay of iron in iron vitriol dreg of yellow sodium and its extract 黄钠铁矾渣及其浸取液中铁的测定
The content of copper in iron vitriol dreg of yellow sodium is relatively high, so it interferes with the determination of iron in dreg by means of potassium dichromate method. 黄钠铁矾渣中铜的含量较高,用重铬酸钾容量法来测定其中的铁时,干扰铁的测定,需预分离才能准确测量。
The dissolving behavior of iron in bauxite tails in vitriol solution was studied. 研究了复杂铝土矿浮选尾矿在酸介质中铁的溶解行为。
Separation of magnetic substance for the preparation of iron extractive mine from waste residue of vitriol 硫酸废渣中用于制备铁精矿的磁性物质的分离
And the iron contents of the iron extractive mines prepared from the magnetic substances were respectively 62.01% ( Longganghu Vitriol Plant) and 67.81% ( Zhuzhou Chemical Plant). 由该磁性物质制备的铁精矿,其含铁量分别为62.01%(龙感湖硫酸厂)和67.81%(株洲化工厂)。
