Others are used for making fertilizers (e.g. apatite for phosphate and sylvite for potassium).
Checking a little further, we found that Potassium Chloride has some alarming properties: first, Potassium chloride occurs naturally as sylvite and is also extracted from salt water and can be manufactured by crystallization from solution, flotation or electrostatic separation from suitable minerals.
The minerals anorthite, albite, and orthoclase named in this figure are all feldspars; sylvite and halite are chlorides of potash and soda.
Sylvinite, sylvite and langbeinite are the most important.
The potassium salts like carnallite, langbeinite, polyhalite, and sylvite are found in ancient lake and sea beds.
K - a light soft silver-white metallic element of the alkali metal group; oxidizes rapidly in air and reacts violently with water; is abundant in nature in combined forms occurring in sea water and in carnallite and kainite and sylvite
Chlorine is a compound of the most common minerals; rock salt or halite (NaCl), sylvite (KCl) and carnallite (MgCl12.
