摘　　要：对翁泉沟硼矿采集的4个矿石样品进行测试,分析得出其主要成分由硼镁石Mg_2[B_2O_4(OH)](OH)和硼镁铁矿(Mg,Fe)_2Fe(BO_3)O_2组成.本物相分析方法通过对样品进行湿法磁选、酸溶方法测定硼镁铁矿中的硼元素.磁选后残渣经酸溶测定硼镁石中硼元素,结果显示其组分与实际地质成矿组分相吻合.实验证明本测试方法对硼矿石物相及硼矿物在自然界中的赋存状态测定分析快速、准确,为当前的硼矿石研究提供了新的思路,能够满足测试要求.Based on the analysis of four samples of ore collected from Wengquangou boron deposit in Liaoning Province, it is concluded that the ore is composed of mainly szaibelyite and ludwigite. In the phase analysis, boron in ludwigite is detected by wet magnetic separation and acid digestion. The remnant digested in acid is used to determine boron in szaibelyite. The result shows that the component tested by this method is in accordance with the ore-forming geological composition. The phase analysis for boron ores and boron minerals in nature is rapid and accurate. It provides a new approach to the study and test of boron ores.
