The future of flotation
Thirty years ago, a cell 30 cubic metres in volume would have been unusually large. Now, 300-cubic-metre cells are commonplace. Outotec has a 500-cubic-metre cell in operation and several 630-cubic-metre cells in delivery, while FL has one 660-cubic-metre cell in operation. Building one big tank does provide energy economies of scale.
