Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

Rather, froth flotation is a promising separation method (Ogunniyi and Vermaak, 2009; Ogunniyi and Vermaak, 2009). In addition to the ability to process small particles, another significant advantage of froth flotation is its higher recovery rates and low energy consumption (Wills and Finch, 2015; Ata, 2012; Kökkılıç et al., 2022).

Flotation rate constant: Constant describing the rate at which the concerning mineral or metal is recovered in the flotation process. Froth zone: Zone in the top of the flotation cell consisting of froth loaded with mainly valuable minerals, which provides extra separation between valuable minerals and gangue minerals.
