ICP-OES Determination of Ta, Nb, Fe, Ti, Sn, Mn, and W in Indian Tantalite-Niobate Ore Concentrate Using Microwave Digestion

摘要: Indian tantalite-niobate ore concentrate is analyzed for Ta, Nb, Fe, Ti, Sn, Mn, and W content using ICP-OES. This paper evaluates two different methods of dissolution the concentrated ore, namely microwave digestion fusion. For samples, a mixture acids (HBF 4 , HCl, HF, etc.) was used complete dissolution. fusion technique, samples were fused with lithium tetraborate metaborate results compared reported values. In latter case, Sn value showed 10% decrease. The method found to be fast, sensitive, accurate, more precise RSD less than 1%. most suitable analytical lines selected Image software ICP-OES system this study. reactivity in various acid mixtures studied are presented discussed.
