| Abstract: | Normally,flotation,gravity and magnetic separation applied for beneficiation on clay-vanadium ores has failed to acquire positive results.Although hydrometallurgy flow of roasting-leaching-precipitating is presently used to obtain high quality V2O5 products directly without any ore dressing process,some problems such as low vanadium grade,large quantity of acid and alkaline consume,huge process cost as well as environmental polluting are resulted.Taking a clay-vanadium ore as subject,an innovative process of scrubbing for head ore-dispersing with reagents-classified concentrating was studied to improve grade of vanadium concentrate as material for hydrometallurgy treatment.The innovative process has been proved to be easily practiced,economic and friendly to environment and indicates a potential commercialized implement. |
