Abstract

Une méthode de flottation par mousse où un jet sous pression d'une boue d'alimentation et un jet sous pression d'air sont envoyés vers un récipient de contact. La boue d'alimentation comprend un mélange de particules d'huile ou de matières hydrophobes et d'eau. La boue d'alimentation et le jet d'air sous pression sont maintenus à certains paramètres de débit et de pression et peuvent se mélanger dans le récipient de contact pour permettre l'ajout de bulles d'air aux particules d'huile ou de matières hydrophobes pour ainsi former des agrégats particules-bulles. Le contenu du récipient de contact est déversé dans un récipient de séparation où lesdits agrégats particules-bulles forment une mousse permettant l'extraction sous forme de concentré.
