Vanadium can be recovered from titaniferous magnetite ore by either of two processes: (1) precipitating a vanadium salt from a leach of ore roasted with salt, or (2) precipitation from a leach of salt-roasted vanadium-rich slag obtained by smelting the ore to make a vanadium-bearing pig iron, which is then blown in a

Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate-kiln furnaces. However, heat induration requires tremendous quantities of energy to produce high-quality pellets, and is consequently expensive. Cold bonding is a low-temperature alternative to heat induration. Pellets can be cold bonded using lime, …
