The proposed process for extracting finely dispersed metal particles from solutions involves floating them with the aid of a carrier. The carrier used is calcium oxide. The process is carried out in the presence of carbon dioxide. The concentration of calcium oxide is maintained at between 1.0 to 1.2 g/dm. The process of flotation is carried out with oxygen and/or hydrogen obtained electrochemically.

Un procédé, qui permet d'extraire de solutions des particules métalliques finement dispersées, consiste à les mettre en flottation à l'aide d'un vecteur constitué d'oxyde de calcium. Ce procédé s'utilise en présence de dioxyde de carbone. La concentration d'oxyde de calcium est maintenue entre 1,0 et 1,2 g/dm. Le processus de flottation intervient à l'aide d'oxygène et/ou d'hydrogène obtenu par la voie électrochimique.
