Where is potassium found on Earth?
Most potassium occurs in the Earth’s crust as minerals, such as feldspars and clays. Potassium is leached from these by weathering, which explains why there is quite a lot of this element in the sea (0.75 g/liter). Minerals mined for their potassium are pinkish and sylvite, carnallite and alunite.
Is potassium nitrate found naturally?
