Short description: A sedimentary rock made of a mechanical mixture of sylvite and halite
Sylvinite is a sedimentary rock made of a mechanical mixture of the minerals sylvite (KCl, or potassium chloride) and halite (NaCl, or sodium chloride).[1][2] Sylvinite is the most important source for the production of potash in North America, Russia and the United Kingdom .[2][3] Most Canada operations mine sylvinite with proportions of approximately 31% KCl and 66% NaCl with the balance being insoluble clays, anhydrite and in some locations carnallite. Other deposits of sylvinite are located in Belarus , Brazil , France , Germany , Kazakhstan, Slovakia and Spain .[4]
