Title
(EN) FORMING EVAPORITE MINERAL PRODUCTS AND THEIR USE AS FERTILISER
(FR) FORMATION DE PRODUITS MINÉRAUX D'ÉVAPORITE ET LEUR UTILISATION COMME ENGRAIS
Abstract
(EN) A method for separating a particulate stream of an evaporite mineral feedstock, the method comprising passing the stream to an air classifier configured to separate the particulate stream into a fine component and a coarse component.
(FR) L'invention concerne un procédé pour la séparation d'un flux de matière particulaire à partir d'une charge de départ minérale d'évaporite, le procédé comprenant l'envoi du flux vers un classificateur pneumatique conçu pour séparer le flux de matière particulaire en un constituant fin et un constituant grossier.
