10 µm iron ore is possible in flotation. The feed is deslimed at 10 µm and the -10 µm stream is considered to be final tailings, even though there is often a significant amount of contained iron ore (Dworzanowski, 2012). Flotation of iron ore is a …

In the cationic reverse flotation of iron ore at alkaline pH (9 to 10.5), gelatinized starch with NaOH is used as an iron ore depressant (Silva et al., 2019). In this process, a desliming step must be applied to remove particles below 10 µm, which can result in large mineral losses ( Gonçalves and Lima, 2020 ).

Column flotation has been successfully applied to iron ore concentration since the 1980s with the goal of reducing silica content and allowing for the efficient production of pellet feed. Since then, columns have been widely used in iron ore processing due to: their lower capital and operational costs when compared to conventional cells their ability to generate higher concentrate grades …
