摘要：

Kind of the elements in chromite ore was firstly deter-mined 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 degrees C for 30 min, then leaching by dilute hydrochloric acid at 80 degrees C 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%.
