锑矿石中金元素的测定

DETERMINATION OF GOLD IN ANTIMONY ORE

矿石中含有丰富的物质,尤其含有很多金属元素,为了对这些金属元素进行提炼与使用,通常会根据矿石金属元素特性采用一些有效的测定方法。而金作为人类较早发现的一种重要金属,其产量低、价格昂贵,一直备受人们的青睐。然而由于金元素在各种矿石中含量差异很大。因此,为了确定矿石的价值,需要对矿石中金元素开展相关测定工作,才能更加准确地判断矿石的价值。为此,文中笔者结合实践,对锑矿石用氯化铵除去锑-火焰原子吸收光谱仪测定金的应用展开探讨,以供参考。

Ores contain abundant substances, especially many metal elements. In order to extract and use these metal elements, some effective methods are usually adopted according to the characteristics of metal elements in ores. As an important metal discovered earlier by human beings, gold has always been favored by people because of its low output and high price. However, the content of gold in various ores varies greatly. Therefore, in order to determine the value of ore, it is necessary to carry out related determination of gold elements in ore, in order to judge the value of ore more accurately. In this paper, combined with practice, the application of ammonium chloride to remove antimony from antimony ores and flame atomic absorption spectrometry to determine gold is discussed for reference.
