摘要
钼的主要矿物有硫化物辉钼矿(MoS2)及其氧化物钼华(MoO3)和铁钼华(Fe2O3.3MoO3.7H2O)。采用浓氨水浸取钼华,继用盐酸(1+1)浸取铁钼华(包括褐铁矿吸附包裹的钼),再用残渣测定辉钼矿。该方法可分离矿石中辉钼矿、钼华和铁钼华,适用于矿石和化探样品中钼物相的分析测定。
Molybdenum minerals are mainly molybdenite （MoS2 ）, molybdite （MoO3 ） and ferromolybdite （Fe2O3 · 3MoO3 · 7H2O）. With strong aqua ammonia to leach molybdite and hydrochloric acid to leach Mo in iron coupling phase（including ferromolybdite）, molybdenite in residue can be determined. The method, which can separate molybdenite, molybdite and ferromolybdite （including Mo adsorbed and packaged by limonite）, is suitable for molybdenite phase analysis in ore samples and geochemical samples.
