The last sub-process of the flotation is the non-detachment/stability of bubble-particle aggregate. The probability of aggregate stability strongly depends on the balance between the attachment forces (F a) and detachment forces (F det). Flotation is only possible when the sum of all attachment forces is greater than the sum of all detachment ...
