Recovery of Coal fines from Rejects by Column Flotation ...

Investigations were carried out using column flotation to recover coking coal fines from the tailings generated at flotation plant of one of theoperating washeries. Columns of different diameter designed and developed by RRL, Bhubaneswar were used in these studies. Washabilitiy studies indicated that the tailings have the potential to yield 60% of clean coal at 15.0% ash level.
