摘要: Abstract Oleate flotation characteristics of hematite have been investigated in this study under a wide range experimental conditions pH, temperature, ionic strength and collector concentration. The revealed the following major features system which include: (a) maximum floatability neutral pH range; (b) an increase response with either solution at room temperature or low strengths; (c) marked temperature—ionic interactions yielding inversion above effect elevated high conditions. None these can be satisfactorily explained by classical theories adsorption based on electrostatic chemisorption model. In paper, results are taking kinetics chemistry oleate into consideration. It is shown that unique solubility oleate, together its tendency to form ionomolecular complexes, largely responsible for observed complex behavior.
