本工作对西南某地金矿的主要含金矿物——黄铁矿、钛铁矿、菱铁矿、磁铁矿、石英和重晶石等6种矿物用仪器中子活化分析测定其中金含量。 1.标准与样品的制备 用王水溶解高纯金箔,制成浓度较高的标准母液,稀释成228.88μg/ml的标准液,保证酸度大于1N。46天后对此标准液作了一次检查,实验证明其含量是稳定的。凡用低浓度的标准液时,都是当时稀释,用后
In this work, the gold content of gold was measured by the neutron activation analysis of 6 kinds of minerals, the main gold-bearing minerals in a gold deposit in a certain place in southwest China - pyrite, ilmenite, siderite, magnetite, quartz and barite . 1. Preparation of standards and samples Dissolve high purity gold foil with aqua regia to make standard mother liquor with high concentration and dilute to 228.88μg / ml standard solution to ensure the acidity is greater than 1N. After 46 days this standard solution was checked, the experiment proved its content is stable. Where a low concentration of standard solution, are diluted at the time, after use
