The Role of Coarse Conditioning Drums in Potash Flotation

Froth flotation is widely used for separating KCl from NaCl and other undesirable components such as carnallite and gangue in the beneficiation of potash. Because the flotation process relies on the hydrophobic and hydrophilic interactions between materials, however, enhancing these relationships is essential to maximizing potash recovery.

What is Froth Flotation?

Mar 04, 2020 · Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.
