Reverse column flotation of iron ore SpringerLink - Know More

Two-stage flotation with the columns could produce a concentrate that was up to 702 Fe at 875 iron recovery, compared to 704 Fe at only 777 iron recovery for four stages of flotation in conventional cells It was shown to be particularly important to operate the columns to recover a maximum of the quartz gangue into the froth...
