Metallurgy

Potassium salts play an important role in metallurgical processes. Potassium chlorides produced by K+S KALI GmbH are applied in surface treatment and galvanising, as hardening and brazing salts, as well as in casting chemistry, as smelting and drossing fluxes.

Aluminium scrap is melted down together using a mixture of sodium chloride and potassium chloride as a flux which removes impurities and converts scrap materials into high-grade alloys. Where transport allows, salt slag resulting from this process can be serviced and recovered in our own recycling facility.
