The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …
For example, clay minerals can affect froth flotation through slime coating but also through other ways, such as affecting froth stability, changing pulp rheology and covering bubble surfaces, that also lower flotation recovery of value mineral (Cruz and Peng, 2016, Farrokhpay and Bradshaw, 2012, Forbes et al., 2014, Ndlovu et al., 2015, …
The adsorption mechanism for most of the anionic collectors on rutile surface is attributed to electrostatic and chemical adsorption. The adsorption of anionic fatty acids onto rutile and other heavy mineral surfaces is postulated to be chemical in nature, this is due to that fact, they adsorb onto these minerals at pH values where the …
