Currently reverse flotation is one of the most common industrial beneficiation methods for separating limonite from gangue minerals (Shrimali et al., 2018, Deng et al., 2021).In this process, the iron ore remains in the flotation tank as a non-floating fraction, while the silicate minerals float up to form a froth layer with the help of attached bubbles.

Froth flotationis an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more simple context, froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is …
