Abstract

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.
