KCl

Potassium chloride is a metal halide salt composed of potassium and chlorine. Potassium chloride is mainly used as a fertilizer, as well as in medicine and pharmaceuticals, in water softeners, as a food additive, and in other industrial applications. Potassium chloride is mostly extracted from minerals such as sylvite, sylvinite, carnallite and from potash in evaporitic deposits formed in sea water and lakes. It can also be extracted from brines and can be manufactured by crystallization from solution, flotation, or electrostatic separation from suitable minerals. Potassium chloride is also a by-product of the production of nitric acid from potassium nitrate and hydrochloric acid. The global potassium chloride market is expected to increase to 3-4% by 2030 mostly due to the increasing food demand driven by population growth.
