Title (EN) PROCESS FOR TAILINGS REMEDIATION
(FR) PROCÉDÉ DE REMÉDIATION DE RÉSIDUS
Abstract: front page image
(EN)The present invention relates to a process for flocculating and dewatering an aqueous mineral suspension. Said process comprises mixing a powdered poly(ethylene oxide) (co)polymer with the aqueous mineral suspension. Said method is particularly useful for the treatment of suspensions of particulate material, especially waste mineral slurries, especially for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.
(FR)La présente invention concerne un procédé de floculation et de déshydratation d'une suspension minérale aqueuse. Ledit procédé consiste à mélanger un (co)polymère de poly(oxyde d'éthylène) en poudre avec la suspension minérale aqueuse. Ledit procédé est particulièrement utile pour le traitement de suspensions de matériau particulaire, en particulier des boues minérales résiduaires, en particulier pour le traitement de résidus et d'autres déchets résultant d'un traitement de minéraux, en particulier, du traitement de résidus de sables bitumineux.
