Title
(EN) METHOD FOR IMPROVING HANDLEABILITY OF CALCIUM CARBONATE CONTAINING MATERIALS
(FR) PROCÉDÉ POUR L'AMÉLIORATION DU CARACTÈRE MANIPULABLE DE MATÉRIAUX CONTENANT DU CARBONATE DE CALCIUM
Abstract
(EN)
The present invention concerns a calcium carbonate containing material having increased bulk density at equal or improved flowability, and a method of producing such a material. The inventive process comprises the step of contacting a calcium carbonate containing mineral powder with a solution or emulsion or dispersion of a binder.
(FR)
La présente invention concerne un matériau contenant du carbonate de calcium ayant une masse volumique apparente accrue à une aptitude à l'écoulement égale ou améliorée et sur un procédé de production d'un tel matériau. Le procédé de l'invention comprend l'étape consistant à mettre en contact une poudre minérale contenant du carbonate de calcium avec une solution ou émulsion ou dispersion d'un liant.
