The Role of Coarse Conditioning Drums in Potash

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.

WO2016079167A1 - Collector for froth flotation of

The invention relates to a flotation process for removal of slimes from potash ores wherein a collector is used which is a propoxylated ethoxylated fatty amine having the formula I wherein R1 is a hydrocarbyl group having 8-24 C-atoms, the sum of all m is on average 2-6, and the sum of all n is on average at least 15 and at most 100.
