•A slow rotating rake was introduced into the lower zone of a Reflux Classifier.•The more uniform dense medium led to increased rejection of coarse gangue.•A step change improvement in gravity separation was achieved.•Ultra-high grade iron ore was produced in a single stage separation. The effect of...
