By using HNO3-HF-HClO4-HCl to melt ore ,a method was developed for determination on eleven elements(V,Mg,Cu,Mn,Pb,Co,As,Ca,Cr,Ni and Mo) in ilmenite by ICP-OES. The decteting lines and instrument working parameters were selected.It was showed that Y-internal standard could eliminate the influenc of the matrix of Ti and Fe on the dectetion. The correlations of calibration curve were all better than 0.999. The recoveries of standard addition were 94%~108% with precision of 0.60%~3.73% RSD for these elements. Results showed that precision and accuracy were satisfactory and the method was rapid and simple.
