Abstract
Carbochlorination of niobium in the tailings of Baogang concentrator was experimentally studied, and the activated carbon was used as the reducing agent and chlorine gas as the chlorinating agent. The effects of the reaction time and the temperature on chlorination rate of niobium in tailings were investigated. The result showed that when the tailings were chlorinated at 800 for 2 h,96.15% of niobium was yield.
