| A new collector BK307 for lepidolite flotation is investigated and
compared with mixed amine. When the dosage of BK307 is equal to that of mixed amine in lepidolite flotation, the recovery of lepidolite concentrate is enhanced from 69.50% to 77;10% in addition to the enhancement of concentrate grade. When the recovery of lepidolite with BK307 is equal to that of mixed amine in lepidolite flotation, the dosage of BK307 decreases approximately by 28% in comparison to mixed amine in addition to the enhancement of concentrate grade. BK307 is proved to be a new and highly selective collector for lepidolite flotation in comparison to mixed amine. |
