Definitions
- the mineral industry is a big consumer of chemicals. These are used in the various stages of transformation / modification / treatment that the mineral materials undergo.
- a step of classifying mineral matter according to the size of the particles which depends in part on the degree of dispersion of the mineral material in a gaseous medium, and of which natural calcium carbonate is a preferred example because of its multiple uses, constitutes one of these steps.
- US 6,139,960 refers to a method of manufacturing fly ash, passing through a classification step in an air classifier, fine fly ash of average diameter between 0.1 and 5 microns that can be pretreated with a silane, a stearate, a aluminate, a titanate or a zirconate.
- Such hydrophobicizing additives do not represent a solution for a person skilled in the art who is looking for an additive which makes it possible, following the classification step, to use the classified material in an aqueous environment.
