Abstract

L'invention concerne un procédé d'obtention de liquide limpide, à partir d'une suspension de solides dans le liquide. Ce procédé consiste à ajouter un agent de floculation polymère à la suspension, à mélanger la suspension pendant au moins 30 s, à ajouter en mélangeant de l'agent de floculation supplémentaire dans la suspension, à soumettre cette suspension à un procédé de séparation solides/liquide par sédimentation ou par flottation pour obtenir un liquide séparé, puis à clarifier le liquide séparé par filtration. On utilise de préférence ce procédé pour séparer des suspensions inorganiques, telles que celles obtenues lors d'un procédé de lessivage du minerai.
