Foam Flotation for ionic metal nano-clusters extraction and separation: Structure of the foam investigated using TOF-SANS
Ion flotation used in separation chemistry is a green alternative to classical solvent extraction process in order to concentrate within a foam, ionic species produced by acidic dissolution of metallic wastes or ores. We aim to study the structure of the foam, a fluid and multi-scaled 3D-structure as a function of its height in a dedicated flotation column and as a function of the the ion concentration in the bulk solution. This study will be carried out in stationary regime and under free drainage conditions. The results will be correlated with the ion extraction efficiencies to optimize the extraction process that will be exploited by an industrial company. Since foams are out-of-equilibrium and fragile systems, we propose to use the TOF mode, only available on D33, to cover a massive and suitable q range from 3.10-3 to 0.3 Å in one instrument setting and in operando.
