Vanadium metal was selectively extracted (95%) with 0.1-0.2 M H 2 SO 3 at 323-363 K, with an ash/reagent ratio of 1/4 and extraction time of 45 min [15]. In a similar study, FA was heated at moderate temperatures (150 • C), a de-carburization and de-sulphurisation (pre-treatment) stage, and finally a smelting step in an electric-arc-furnace [2].
