Chemical reagents got reacted with the desired mineral in the flotation process. The effectiveness of the flotation technique is dependent on four factors: the degree of oxidation of the ore, the number of copper minerals present, the nature of the gangue and the presence of iron sulphides.
Reverse flotation of iron ore is now drawing more attention in iron ore industry as an efficient beneficiation process (Ma et al., 2011; Filippov et al., 2010; Araujo et al., 2005; Houot, 1983). In reverse cationic flotation, silica and silicates are floated after depressing the iron oxide by suitable reagents such as starch, dextrin, and CMC.
