An investigation of froth stability in reverse flotation

Aug 15, 2020 Generally, reverse flotation by cationic surfactants or anionic surfactants is used to remove silicate gangues from fluorapatite ores. However, a cationic collector is more sensitive to slime than an anionic collector, and a large amount of overly stable froth is produced in reverse flotation with cationic surfactants (Ruan et al., 2019).
