Abstract

La présente invention concerne un procédé de flottation pour un charbon présentant une faible flottaison comprenant les étapes consistant à : fournir, au moyen d'une pompe (E), une solution contenant des nanobulles (5) à un réservoir de mélange de boue minérale (F), et à fournir simultanément une quantité appropriée de charbon (7) et un réactif de flottation (8) au réservoir de mélange de boue minérale (F) ; et fournir, au moyen d'une pompe d'alimentation en matière (G), un mélange de boue minérale (9) à une colonne de flottation à micro-bulles statique à contre-courant (H) pour subir une flottation, ce qui permet d'obtenir deux produits, un charbon fin (10) et un résidu (11). Le réactif de flottation est constitué des composants suivants : un kérosène, de l'éthylthionocarbamate d'isopropyle, un Tween 40, un sulfate d'éther d'alcool de sodium, l'acide p-toluènesulfonique, un Span 60, l'anhydride phtalique, le dodécylbenzène sulfonate de sodium et l'anhydride benzènedicarboxylique. Le procédé exploite la propriété des nanobulles de se rassembler préférentiellement au niveau d'une surface hydrophobe, augmentant la différence d'hydrophobicité entre le charbon fin et la gangue de charbon. Le fait que les nanobulles se rassemblent réduit également de manière significative une boue fine recouvrant une surface de particule de charbon, réduisant ainsi considérablement la contamination provoquée par la boue fine, et augmentant la vitesse de recyclage du charbon fin.
