Abstract：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%.
