    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.

    Potash Production ArrMaz

    The flotation reagents introduce air bubbles to which the potash can attach and rise to the surface for collection. The correct selection of flotation reagents is critical for successfully maximizing both the amount of potash recovered from the ore and maximizing the purity of the potash by separating out unwanted material.
