Abstract
La présente invention concerne un procédé pour traiter le stuc qui comprend les étapes consistant à introduire une certaine quantité de particules de stuc dans un réacteur, les particules de stuc comprenant du sulfate de calcium semi-hydraté et/ou de l'anhydrite de sulfate de calcium, ainsi que du sulfate de calcium dihydraté ; et à traiter les particules de stuc à une température d'au moins 100 °c et une humidité d'au moins 70 %. Pendant l'étape de traitement des particules de stuc, la masse volumique apparente des particules de stuc à l'intérieur du réacteur est d'au moins 1 g/cm
