Efficiency and intensity of the flotation of isostructural, tetrahedral oxyanions with the cationic (R)4N+ type surfactant were examined, exemplified by the case of the diluted aqueous solutions of phosphorus(v), molybdenum(vi) and rhenium(vii) at concent rations of 1 × 10−4, 5 × 10−5 and 1 × 10−5 kmol m−3. No direct relation was found between the flotation efficiency and the charge and size of the examined ions. For ions of equal charge, the Grieves entropy criterion15 was obeyed in most cases. |
