Bubble and Foam Separations— Ore Flotation P. …
A brief description of various flotation processes is given below. It is to be noted that, although froth flotation of ores is the only process that has been used industrially on a large scale, other flotation techniques have considerable potential for treating dilute solutions and industrial wastes.
Flotation processes are based on the different surface wettability properties of materials (Wang et al., 2015). In principle, flotation works very similarly to a sink and float process, where the density characteristics of the materials, with respect to that of the medium where they are placed are at the base of the separation.
