Zusammenfassung:	An inerting process for impurities in aggregates intended for preparation of hydraulic or hydrocarbon compositions, includes adding to the composition or to one of its constituents a cationic polymer corresponding to at least one derivative of a natural polymer or a polymer of natural origin selected from the group including dextrin (in particular yellow dextrin and white dextrin), chitosan, chitin, alginates, hemicellulose, pectin, polyols or proteins.
