An Overview Of Potash Flotation

More than 70% of potash is produced worldwide by froth flotation. Flotation of potash was developed in the early 1930s. Amines are widely used for flotation of sylvite (KCl) from halite (NaCl) and insoluble materials such as clays. Amine collector is also absorbed by clays. Therefore, clays are ...

The effect of conditioning on Froth Flotation

Microflotation was chosen as the technique used to relate flotation response to adsorption. The advantage of microflotation over other flotation systems, is its use of very small quantities of mineral and the ability to operate the system without the complicating froth phase.

Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be "skimmed" from the surface of "slurry" that is "foamed" with the assistance of specific chemicals, water and air bubbles.

Froth Flotation Process

For the most part the flotation processes are limited in effectiveness to the beneficiation of deslimed ore pulps, especially so when the tin grades are low. One class of collectors that has been advocated is the sulfosuccinamates optionally used with fuel oil to control froth. Flotation is carried out at a pH below 5.
