Method of separating sylvite from sylvinite ore
Separation of sylvite from potash ore such as sylvinite ore may be accomplished by a variety of methods. one method, the potassium chloride is extracted with a hot solution saturated with respect to sodium chloride. The solution is flash-cooled to deposit potassium chloride crystals which are then filtered, Washed, and dried.

What is potash?
Potash is the name for the group of minerals that provide potassium for plant growth. It is a 'must have' fertiliser for crop production. 90-95% of potash is used in agriculture as fertiliser. The most common type of potash is Muriate of Potash (MoP) which is used to maintain soil fertility and improve plant health.
