The performance of floatex density separator (FDS) for alumina removal from iron ore fines of size <1˙0 mm has been studied. Screw classifier feed containing 4˙28% alumina has been used as the raw feed material. Desliming in hydrocyclone helps to reduce the alumina content down to 3˙39% by removing high alumina bearing ultrafine particles.
