Abstract
Il est décrit des procédés/méthodes de mise en uvre pour le traitement de résidus fins contenant des plaquettes dargile, y compris lajout dun agent de pillage, comprenant des cations trivalents et/ou des cations tétravalents, à des résidus fins pour transformer au moins une partie des plaquettes dargile en solides couches pillées. Le réglage dau moins un pH solubilisant, dun potentiel zêta et dune concentration de lagent pillant peut être réalisé pour faciliter la solubilisation des cations trivalents et/ou tétravalents et une diffusion ultérieure pour lintercalation entre les surfaces basales des plaquettes dargile pour former un intercalaire de piliers thermiquement stable. Les résidus traités sont en outre déposés en vue dune consolidation ultérieure dans le temps pour former un gisement consolidé qui aboutit à une forme terrestre géotechnique et géochimique stable dans une période plus courte que selon les techniques classiques de dépôt/consolidation.
