Abstract

La présente invention a pour objet un procédé pour la préparation d'un clinker de ciment à partir de schistes houillers ou de toute autre matière minérale susceptible de libérer un certain pouvoir calorifique. Elle est caractérisée en ce que, selon ce procédé, on soumet à la clinkérisation un cru constitué pour partie de schistes houillers préalablement calcinés et pour partie de matières additionnelles pouvant contenir du calcaire et de l'argile, les matières additionnelles étant au préalable au moins partiellement décarbonatées.
