Abstract

L'invention porte sur un procédé pour la fabrication de compositions d'engrais contenant du soufre, comprenant les étapes consistant à : a) se procurer une suspension épaisse d'au moins une matière d'engrais à base de phosphate choisie dans le groupe constitué par les phosphates d'ammonium, les composés à base d'azote-phosphore-potassium (NPK) à base de phosphate d'ammonium, les superphosphates et les roches phosphatées partiellement acidulées; b) mettre ladite suspension épaisse en contact avec au moins un tensioactif anionique et du soufre élémentaire; c) introduire le mélange obtenu dans l'étape b) dans une unité de granulateur afin d'obtenir des granulés de la composition d'engrais, ladite ou lesdites matières d'engrais à base de phosphate étant présentes en une quantité dans la plage d'au moins 50 % en poids, le soufre élémentaire étant présent en une quantité dans la plage de 1 à 25 % en poids et le tensioactif anionique étant présent en une quantité dans la plage de 0,001 à 3 % en poids sur la base du poids global de la composition d'engrais. La présente invention porte également sur une composition d'engrais.
