halite salt flotation optimization


Mineral Processing Solutions

Carnallite is a naturally occurring dual salt commonly found in the presence of other salt-type minerals such as halite. Under certain conditions, significant amounts of carnallite can be formed by means of solar evaporation in ponds filled with saturated brine solutions.

To this end, freshwater was pumped slowly through a horizontal borehole in rock salt cores. Owing to fast halite dissolution kinetics, high solubility, and slow inflow rate, halite dissolution took place …
