| 摘 要： | 钼矿石的主要矿物有辉钼矿,其次是钼钨钙矿、铁钼华矿、钼华矿和钼酸铅矿。样品经碱熔融分解,硫氰酸盐比色法测定总钼;利用电感耦合等离子体质谱法测定氢氧化铵溶解钼华中的钼;酒石酸溶解钼钨钙矿中的钼;碳酸钠溶解钼酸铅矿中的钼;盐酸溶解铁钼华矿中的钼。方法对不同钼矿石样品进行了5种钼矿石物相分析,结果与实际地质成矿组分符合。

| Abstract: | The main minerals in molybdenum ores are molybdenite (MoS2), powellite , ferrimolybdite (Fe2O3·3MoO3·7H2O), molybdite (MoO3)and wulfenite (PbMoO4). Samples were fused by alkali mixture and the total molybdenum in the sample was determined by sulfocyanide colorimetry. Molybdenum in mineral phases of molybdite, powellite, wulfenite and ferrimolybdite was extracted by ammonium hydroxide, tartaric acid, sodium carbonite and hydrochloric acid, respectively and then determined by ICP-MS. Five molybdenum mineral phases in six kinds of molybdenum ores were analyzed and the results were in accordance with the geological facts. |
