中文摘要：

采用ICP-AES法对铬铁矿首先进行定性分析，确定了铬铁矿中含有的元素种类;经过分析发现铬铁矿中含有Cr，Fe，Al，Mg，Zn，Co，Ni等29种元素。然后根据定性分析的结果，对铬铁矿中的主要元素Cr，Fe，Al，Mg，Ca，Ti，Si，Mn，V的含量进行测量。铬铁矿样品的前处理分两步进行，首先用碳酸钠-四硼酸钠在950 ℃下熔融30 min，然后用稀盐酸在80 ℃下浸取10 min，即可将样品完全溶解。实验结果表明，该方法的相对标准偏差为0.48%～2.05%，加标回收率为90.5%～111.3%，分析精确度满足要求。

英文摘要：

Kind of the elements in chromite ore was firstly determined by ICP-AES. Twenty nine elements, such as Cr, Fe, Al, Mg, Zn, Co and Ni, were contained in the chromite sample based on the qualitative analysis. Then the contents of main elements Cr, Fe, Al, Mg, Ca, T, Si, Mn and V were measured. The chromite samples processing procedures have two steps, the first is decomposition by nitrate carbonate and sodium tetraborate at 950 ℃ for 30 min, then leaching by dilute hydrochloric acid at 80 ℃ for 10 min. The method showed satisfactory precision and accuracy with the RSDs between 0. 48% and 2.05% and the recovery rates between 90.5% and 111.3%.
