摘要： The invention relates to a neutralization and granulation method wherein a neutralizing foam is used as granulation adjuvant. The neutralizing foam was previously obtained by mixing an anionic surfactant in its acid form, which was expanded using a gaseous medium, and a highly concentrated, aqueous alkaline component, which was expanded using a gaseous medium. The neutralizing foam has an average pore size of less than 10 mm, preferably less than 5 mm and especially less than 2 mm.
