Two flotation models, particle at the liquid–gas interface and particle–bubble aggregate, both based on balance of forces, were used for evaluation of experimental data relating the maximum size of floating particles d max and their advancing contact angle
Instead of using acceleration constant a for modeling and relating the maximum size of floating particle d max and advancing (detachment) contact angle θ d, for constant particle density ρ p, medium density ρ l, surface tension σ, and flotation cell dynamics, an empirical apparent flotation cell constant A, can be used It can be determined by approximation of the experimental data with a
