A Model Structure for Size-by-Liberation Recoveries in Flotation

This communication presents a model structure for the flotation recovery of middling particles (10–90% liberation). Fourteen datasets from literature were studied (galena flotation), which involved different systems and operating conditions. The responses allowed flexibility to be evaluated under range profiles. modelling results showed that galena can characterized by interaction between linear function concave (e.g., Gamma model), account liberation particle size effects, respectively. Liberation also impacts location dispersion dependence on size. proposed there was adequate with five parameters, leading adjusted coefficients determination ranging 0.863 0.998 datasets. Thus, an alternative approach is proposed, represents few parameters.
