Manufacturing Relationships. Distributing Quality


Alumina is produced through multiple different methods such as by refining bauxite, Bayer process, sinter process or a combination of the Bayer and sinter processes. 

JAS manufactures chemical additives for several stages of the industrial alumina process.

JAS alumina processing additives
