Title (EN) METHODS FOR ENHANCING EFFICIENCY OF BITUMEN EXTRACTION FROM OILSANDS USING ACTIVATED CARBON CONTAINING ADDITIVES
(FR) PROCÉDÉS D'AMÉLIORATION DE L'EFFICACITÉ DE L'EXTRACTION DE BITUME À PARTIR DE SABLES BITUMINEUX À L'AIDE D'ADDITIFS CONTENANT DU CHARBON ACTIF
Abstract: front page image
(EN)Methods are provided for separation of bitumen from oil sands ore having a bitumen content higher than about 6%. Activated carbons, or combinations of activated carbons and caustic are used as process additives for ore-water slurry- based bitumen extraction processes or in situ bitumen recovery processes. These additives promote breakdown of adhesion between clay minerals and bitumen, resulting in the enhanced efficiency of extraction of bitumen from oil sands ore.
(FR)L'invention concerne des procédés pour la séparation de bitume à partir de minerai de sables bitumineux présentant une teneur en bitume supérieure à environ 6 % Des charbons actifs, ou des combinaisons de charbons actifs et de soude caustique, sont utilisés comme additifs de traitement pour des procédés d'extraction de bitume à base de boue de minerai-eau ou des procédés de récupération de bitume in situ. Ces additifs favorisent la rupture de l'adhésion entre les minéraux argileux et le bitume, ce qui permet d'améliorer l'efficacité d'extraction du bitume du minerai de sables bitumineux.
