Abstract

La présente invention se rapporte à la production d'engrais minéraux. Le procédé de cette invention permettant de produire un engrais à base de calcium et d'ammoniac consiste à mélanger du nitrate d'ammonium en fusion avec une matière première de carbonate broyée comprenant un carbonate de calcium ou un carbonate de calcium et de magnésium, à granuler le mélange puis à faire sécher et à refroidir le produit ainsi obtenu. Une couche de sulfate de calcium ou de sulfate de calcium et de magnésium ayant pour effet de limiter l'interaction entre la matière première broyée et le nitrate d'ammonium en fusion est formée sur la surface des particulesde matière première au moyen du traitement, avant le mélange, de la matière première de carbonate broyée avec un hydrosulfate d'ammonium selon une concentration comprise entre 20 et 45 % en masse à une fraction massique de 1: (0,01-0,3), ce qui permet de réduire la teneur en nitrate de calcium ou en nitrate de calcium et de magnésium de l'engrais et de réduire les pertes d'azote ammoniacal pendant sa production.
