bubbles. Such flotation methods are not suitable for wastewater treatment and oil extraction. Jameson (Clayton et al., 1991) developed an improved version of induced-air flotation, which was more successful in the removal of fats, oil, and grease from the wastewater. Another flotation method, called dissolved-air flotation (DAF), is much more

The challenge in iron ore flotation performance is the balance between the high level of quartz recovery with the minimum iron loss in the froth. The strategy in chemicals used should consider an optimum combined system to perform the simultaneous functions assigned to the reagents. Non-ionic surfactants MIBC and Dowfroth 1012 are more ...

The requirement for higher quality pellets demands that the silica content be lowered to levels ranging from 0.25% – 2.0% SiO2. Reverse flotation (silica is floated away from the iron concentrate) has proven to be an economical and effective method for reducing the concentrate silica content to very low levels.
