Investigation of the reverse flotation of iron ore in
May 01, 2020· Both chemical variables and hydrodynamic conditions within the flotation cell affect the recovery and selectivity of the flotation process. Reverse flotation of iron ores can be performed by anionic and cationic collectors, while iron oxides are depressed by various chemicals such as starch, dextrin and sodium carboxymethyl (Tohry et al., 2019).
