Mechanisms of Dodecylamine Flotation of Quartz - Taylor
If the Krafft temperature is exceeded increased hydrophobicity and flotation will probably occur only after the critical micelle concentration (CMC) is exceeded within the quartz-solution interface. In both cases if pH is still further increased ultimately either the solubility or the CMC would be exceeded within the bulk of the solution provided the total amount

Two-stage reverse flotation process for removal of carbonates
2018.10.6 Flotation in this case is carried in two stage operation. Anionic–cationic double reverse flotation was found to be an appropriate method to upgrade grade phosphate rocks. The two steps process is to float the carbonates at pH = 4.8–5.2; the second stage includes flotation of the quartz at pH = 7.8–8.5.

2020.8.31 Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp
