Column flotation of iron ore sciencedirect

May 01, 2007 Two-stage flotation with the columns could produce a concentrate that was up to 70.2% Fe at 87.5% iron recovery, compared to 70.4% Fe at only 77.7% 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

    Today column flotation has become . an accepted means of froth flotation for a fairly broad range of applications, in particular the cleaning of sulfides (copper, zinc, lead and molybdenite) and the flotation of iron ore, phosphate and coal. Flotation columns differ dramatically from mechanical flotation machines in . several ways:

    May 01, 2018 The flotation rate constant is also affected by particle size. Many iron ore concentrators use the quantity of +100 mesh (.15mm) material in the flotation feed as a measure of the performance of the grinding circuit. 100 mesh particles are well within normal flotation range and present no
