Hoffmann Mineral was founded in 1903 by Franz Hoffmann as a steam washing plant for Neuburg siliceous earth. At the time, the most important field of application for the siliceous earth was as a polishing agent and for household care products. In 1950, the company turned into Sonax GmbH.[1] 1971 übernimmt Hoffmann Mineral die Kieselerdesparte des Wettbewerbers Globus-Werke und ist seitdem der einzige Produzent von Neuburger Kieselerde. In 1971, Hoffmann Mineral took over the siliceous earth division of the competitor Globus-Werke and since then, they are the only producer of Neuburg siliceous earth. The last underground mine was closed in 1979, and since then, siliceous earth is only extracted through open pit mining[2] In 1991, Manfred Hoffmann junior took over the company and is the fourth generation to manage the company.[3]
