May 01, 2020  1. Introduction. Flotation is a selective process for separating minerals from each other based on particle hydrophobicity. The flotation separation efficiency depends on the recoveries of the mineral species by both true flotation and entrainment (Cilek, 2009, Neethling and Cilliers, 2009, Wang et al., 2015).Both chemical variables and hydrodynamic conditions within the flotation cell affect ...
