A study on the recovery of fine chromite from UG2 tailings
The final chromite concentrate returned a CaO grade of less than 0.35 %. Importantly, comparative results at the same grade and recovery demonstrated the significance of desliming prior to flotation, in reducing the dosage of the Flotinor V-2711 collector by more than 60 % when compared to an un-deslimed feed, from an average of 868 g/t to 283 g/t.
