  • Potassium (K) - Chemical properties, Health and ...

    Potassium in the environment. 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.

    Formula: KAlSi 3 O 8 Monoclinic or Triclinic Description: Potassium feldspar refers to any of the three polymorphs microcline, orthoclase or sanidine. The distinction between these minerals can be made with certainty only after detailed X-Ray analysis. This has not kept the terms from being used freely in the literature without such analyses being made.

  • Potassium - Chemical Elements

    It can be even said that potassium is a trace elment — it forms only 160 ppm 1 (0.16%) of the bulk Earth. How is it possible? It is an important constituent of K-feldspar and mica and these are among the main components of granite — a rock type we are all very familiar with. Micas are platy silicate potassium-rich minerals.

    Think pink is the motto for potassium feldspar. The image to the left shows several large grains of the potassium feldspar, orthoclase; note the pinkish cast. As orthoclase is a feldspar, you should also see the stair-step cleavage characteristic of feldspars. Unfortunately, all potassium feldspar is not pink, microcline is usually white.
