Abstract

La présente invention concerne le traitement de résidus de sables bitumineux à l'aide de chaux CaO ou de chaux CaO et de CO2 dans le but d'atteindre une consolidation améliorée sans séparation des solides présents dans les résidus et de récupérer l'eau rejetée présentant des propriétés chimiques acceptables afin de l'utiliser dans le processus d'extraction du bitume. Les résidus sans séparation sont produits à partir d'un mélange de sousverse du cyclone et de sousverse épaississante ou encore d'un mélange de sousverse de cyclone, de sousverse épaississante et de résidus fins mûrs. Cela se fait grâce au traitement du mélange de résidus avec du CaO ou encore du CaO et du CO2, selon des dosages appropriés, avec la production simultanée connexe d'eau rejetée, qui présente des concentrations plus faibles de Ca2+, de Mg2+, de Na+, de Cl- ions, de particules ultrafines et d'espèces organiques colorantes.
