铬铁矿是较难分析的复杂矿物。由于我国岩矿测试工作者的多年努力,特别是六十年代以后的大量实践,在铬铁矿分析方面积累了丰富的经验,取得了很大的进展。概括地说,这些成果是:在铂坩埚中用过氧化钠半熔或用过氧化钠-氢氧化钠熔融分解样品获得成功;铬的分离普遍采用了离子交换分离技术,尤其是用干燥的阴离子树脂分离铬和在碱性介质内离子交换分离铬,操作简便,分离完全;提出了不少快速、合理的分析流程,研究并提供了一套包括痕量铂族元素在内的全分析方法;出版了总结我国分析方法的专著——《铬铁矿石分析》;研制并发行了我国的铬铁矿石标准样品。与国际上同类矿种的分析水平相比,我
Chromite is a complex mineral that is harder to analyze. Due to years of hard work of rock and mineral test workers in our country, especially a great deal of practice since the 1960s, we have accumulated rich experience in chromite analysis and made great progress. In summary, these results are: Success in the semi-melting of sodium peroxide in a platinum crucible or the melting and decomposition of samples with sodium peroxide-sodium hydroxide; the separation of chromium generally employs ion exchange separation techniques, especially with dry anions Resin separation of chromium and ion exchange in alkaline medium separation of chromium, easy to operate, the separation is complete; proposed a number of rapid and reasonable analysis of the process to study and provide a set of trace platinum group elements, including the full analysis method; Published monographs summarizing China’s analytical methods - “chromite analysis”; developed and published China’s standard samples of chromite ore. Compared with the international analysis of similar minerals, I
