Improving recovery of iron using column flotation of iron

2020-11-1  Below 37 µm: 66.2% of the mass and 40.1% of the Fe content. Column flotation tests were performed with iron ore slimes. The column having 5.1 cm in diameter and a total height of 6.0 m was used. The %s in the conditioning phase and in the column feeding were kept at 35% and 25%, respectively.
