Jan 2, 2012 In practice, iron ore often contains a few percent SiO2, even after repeated magnetic or hydraulic separation, due to the presence of locked siliceous gangue minerals. To further upgrade the concentrate, froth flotation has been established as an efficient method to remove impurities from iron ore …

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.
