Abstract
A process for producing granulated particles from a powder which is insoluble in water, employs dimensions of the formed granulated particles which are substantially larger than those of the powder grains. The powder is mixed with an aqueous solution of a cellulose chosen from among methyl cellulose, hydroxypropyl methyl cellulose, etheric hydroxybutyl methyl cellulose. Then droplets of this mixture are made to fall into an aqueous solution of at least one metallic salt or metallic hydroxide which does not react with the particles.
