钼矿石中氧化钼的浸取条件研究

Extraction of MoO_3 from Molybdenum Ores

摘要: 以Cu~(2+)-稀HCl混合溶液为MoO_3的选择性溶剂,Cu~(2+)能有效地消除酸溶硫化物溶解时产生的H_2S对MoO_3测定的干扰。选用催化极谱法测Mo可进一步简化操作手续,提高测定灵敏度。所拟方法用于一般钼矿石物相分析,尤其对含酸溶硫化物较多的矿石均能得到满意的结果。

Abstract: A Cu2+-HGl solution is proposed as a selective solvent for MoO3 in phase analysis of molybdenum ores. The interference with the determination of Mo, caused by the H2S produced from the acid soluble sulfides, can be effectively eliminated by the Cu2+ in th
