2014-10-28 · The amenability of reverse cationic column flotation technology for recovery of iron values from screw classifier overflow or slimes (d80: 40.5 µm) of an operating washing plant has been established by laboratory scale studies. Selection of proper collector plays a key role and needs to be evaluated based on the type of ore and nature of the gangue. A typical screw classifier overflow analyzing 60.43% Fe, 6.88% SiO2 and 3.26% Al2O3
