Qualitative and Quantitative Analysis of Various Elements in Chromite Ore by ICP-AES
Kind of the elements in chromite ore was firstly determined by ICP-AES.Twenty nine elements, such as CrFeAlMgZnCo and Ni, were contained in the chromite sample based on the qualitative analysis.Then the contents of main elements CrFeAlMgCaTSiMn 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%.
