- •
Low Br and high Rb concentrations occur in sylvite derived from carnallite.
- •
Sylvite and halite are separated from sylvinite by flotation method.
- •
Redistribution of Br and Rb between solid and liquor phases due to KCl re-crystallization.
- •
Driving force is a difference between Mg2 + dissolution rates and K+ crystallization rates.
