Recovery of Iron Ore Tailings byColumn Flotation

accounted for a increase in the content of iron and a con- siderable reduction in the SiO2 content in the iron con- centrate, while the recovery of the mass and of Fe fell. It is important to add a depressant agent to the iron mi- nerals in the iron ore reverse flotation. In this work, corn starch and CMC (carboxymethylcellulose) were used.
