    Theoretical and experimental studies have been performed to analyze the entrainment of both hydrophilic and hydrophobic particles flotation. A new model is proposed for the entrainment based on the water trend. Two sets of timed flotation experiments were carried out to validate the model. These experiments were realized with quartz and pyrite as the only in the pulp and ...
