A process for producing from olivine precipitated silica with controlled specific surface area and high degree of purity. The process comprises adding olivine in a controlled manner to a heated mineral acid solution; after separating undissolved olivine and filtering the silica is slurried in aqueous solution to obtain a low viscosity high solid content silica slurry that can be efficiently degritted and dried with a relatively low energy consumption. The obtained silica can be in powder, bead or granule form and preferably has a specific surface area of at least about 100 m2/g.

L'invention porte sur un procédé de production de silice précipitée avec de l'olivine et ayant une surface spécifique contrôlée et un haut degré de pureté. Le procédé consiste à ajouter de manière contrôlée de l'olivine à une solution acide minérale chauffée; puis après séparation de l'olivine non dissoute et filtration, mettre la silice en suspension en solution aqueuse afin d'obtenir une boue de silice de faible viscosité, à haute teneur en solides qui peut être efficacement dessablée et séchée avec une consommation d'énergie relativement faible. La silice obtenue peut se présenter sous forme de poudre, billes ou granulés et a, de préférence, une surface spécifique d'au moins environ 100 m?2¿/g.
