dc.description.abstractThis paper aims to research the influence of the particle shape of the iron oxide-containing toner on flotation efficiency and to test first-order and second-order kinetics models to determine the model which better describes the flotation of the coarse plate-like particles. Hallimond tube flotation were carried out on two toner samples (regular round plate-like and irregular plate-like particles), with no collector in use. Contact angle measurements were conducted by sessile drop method. The results show that both samples have the same high value of contact angle which indicates that the toner samples are hydrophobic. High toner flotation recovery is achieved with round plate-shaped toners after prolonged time and flotation kinetics of toner was described by classical first order flotation model. The toner with the irregular plate-shape has reduced flotation recovery even after a long time of flotation and flotation kinetics of toner was described by modified first order flotation model. It should be emphasized that no significant differences were observed when measuring the contact angle of samples, and that the lower recovery obtained for sample with irregular plate-like particles can be attributed to the different shape of the particles.
