Uses
Carnallite is mostly used in fertilizers. It is an important source of potash. Only sylvite outranks carnallite’s importance in potash production. Both are uncommon because they are some of the last evaporites to form. Soluble potassium salts are the main sources for fertilizer. This is because the potassium is difficult to separate from insoluble potassium feldspar. Carnallite is a minor source of magnesium worldwide; however, it is Russia’s main source.
