Feldspar exists in different phases such as microcline, albite and anorthosilicate. The feldspar has an average chemical composition of 62% SiO2, 26% Al2O3, 8% K2O, 3% Na2O and 1% CaO as the main constituents. In order to extract potassium, chemical leachants such as HCl, H2SO4 and HNO3 were tried with different concentrations.

Potassium is a light, very soft, silvery-white metal. It is even more violently reactive with water than is sodium. It is so reactive with oxygen, that if exposed to air, it will tarnish to a grayish color in seconds. Potassium occurs with an abundant radioactive isotope, K40. Consequently, potassium metal is almost always faintly radioactive.
