Flotation reagent. ... Collecting reagents increase the angle of contact of the three-phase system and, therefore, the interfacial tension between the particle and the liquid. Among useful reagents of this type are fatty acids and soaps. The usefulness of collectors is enhanced by activating reagents ... Depressing reagents accomplish the opposite task. 1, record 1, English, - collecting%20reagent

La flottation est ainsi utilisée pour la séparation sélective de certains solides contenus dans une pulpe et pour leur concentration. Pour opérer cette sélection, on utilise des réactifs collecteurs, particulièrement hydrophobes, qui ont pour but d'augmenter la répulsion vis-à-vis de l'eau du minerai que l'on désire sélectionner. Les réactifs dépresseurs de gangue auront pour but au contraire d'augmenter la mouillabilité de la masse de matières que l'on ne désire pas retenir. 1, record 1, French, - r%C3%A9actif%20collecteur

Record number: 3, Textual support number: 1 OBS
The property of surface activity is usually due to the fact that the molecules of the substance are amphipathic or amphiphilic, meaning that each contains both a hydrophilic and a hydrophobic(lipophilic) group. This assumes that one of the two phases is aqueous, and the other non-aqueous. If both are non-aqueous(e. g. oil/air), molecules containing organophilic and organophobic groups may be amphipathic and surface active. 3, record 3, English, - amphipathic%20molecule

La propriété d'une activité de surface est généralement due au fait que les molécules de la substance sont amphipathiques ou amphiphiles, ce qui signifie que chacune contient à la fois des groupes hydrophiles et hydrophobes (lipophiles). Ceci implique que l'une des deux phases est aqueuse et l'autre non aqueuse. Si les deux phases sont non aqueuses (par exemple, huile et air), les molécules contenant des groupes organophiles et organophobes peuvent être amphipathiques et tensioactifs [sic : tensioactives]. 3, record 3, French, - mol%C3%A9cule%20amphipathique
