Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. The mining industry is the largest end user of froth flotation chemicals.
The additional reagents required for the zinc flotation consist of sodium sulphide, primary amines and a frother which are added to the conditioner discharge in the order stated and prior to entering the flotation machines.
Summary. The course is divided into two broad sections: the science (surface chemistry) of flotation, and; flotation technology and practice. The course content is structured to provide a review of the current state of the fundamentals and technology of froth flotation.
Froth flotation and film (skin) flotation are the best examples of flotation taking place on the gas–liquid interface. Film flotation occurs on a free water surface. Particles are gently fed onto the free surface, allowing the separation of hydrophobic (water-repelling) particles, which attach to the free surface, from non-floatable ...
