The 242.795 nm on ICP-AES for the gold analysis was the most sensitive wavelength which was also interfered severely by the spectra of other metal ions such as manganese, chromium, cobalt, and iron. In order to analyze the gold in ore, the gold must be separated from the interfering ions. The best solvent for separation of gold in ore solution was 10 % n-hexane contained MIBK mixed solvent. The gold recovery was 97.5 % from mixed metal solution contained about 2 M <TEX>$HNO_3$</TEX> and 0.5 M HCl.
