Tóm tắt:
Graphite ore of Yên Thái areas have flaky forms thus single-step flotation usually gives low performance. For obtaining graphite concentrate of more than 90 % c grade with 0 high recovery, it is normally to apply multiple steps flotation using mixtures of flotation reagents (collectors and frothers). This report presents the findings of the study on flotation of graphite ores of Yên Thái, Yên Bái in flotation circuits with 1 rougher operation, 1 scavenging flotation and 4-8 cleaning operations using self-made mixture of flotation reagents. The obtained concentrates have reached the purity of more than 85-90 % c with a overall recovery close to 70 %.
