Title (EN) METHOD FOR PRODUCING POTASSIUM CHLORIDE GRANULAR MATERIALS
(FR) PROCÉDÉ DE PRODUCTION DE GRANULÉS DE CHLORURE DE POTASSIUM
(DE) VERFAHREN ZUR HERSTELLUNG VON KALIUMCHLORID-GRANULATEN
Abstract:
(EN) The invention relates to a method for producing potassium chloride granular materials from a crystalline potassium chloride raw material, wherein, before the granulation process, the potassium chloride raw material is treated with at least one alkali metal carbonate and at least one metaphosphate additive in the presence of water. The invention further relates to the potassium chloride granular materials that can be obtained according to the method.
(FR) La présente invention concerne un procédé de production de granulés de chlorure de potassium à partir d'une matière première cristalline constituée de chlorure de potassium, ledit procédé consistant à traiter la matière première constituée de chlorure de potassium, avant la mise sous forme de granulé, avec au moins un carbonate de métal alcalin et au moins un additif constitué de métaphosphate en présence d'eau. L'invention concerne également les granulés de chlorure de potassium obtenus selon ce procédé.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Kaliumchlorid-Granulaten aus einem kristallinen Kaliumchlorid-Rohmaterial, wobei man das Kaliumchlorid-Rohmaterial vor der Granulierung mit wenigstens einem Alkalimetallcarbonat und wenigstens einem Metaphosphat-Additiv in Gegenwart von Wasser behandelt. Die Erfindung betrifft auch die nach dem Verfahren erhältlichen Kaliumchlorid-Granulate.
