Zusammenfassung:	This disclosure relates to a froth-interaction flotation unit (1000), a mineral processing apparatus, and a method for separation of input slurry using froth- interaction flotation. The froth-interaction flotation unit (1000) comprises a tank (1100) for holding a volume of slurry (1001) and a froth layer (1002), a coarse slurry feeding arrangement (1200) for feeding coarse slurry (1201) to the froth layer (1002), a flotation gas supply arrangement (1300) for supplying flotation gas (1301) into the volume of slurry (1001), a fine slurry feeding arrangement (1400) for feeding fine slurry (1401) into the volume of slurry (1001), and a classification arrangement (1600) configured to classify the input slurry (1601) to form a coarser slurry fraction (1602) and a finer slurry fraction (1603), to feed the coarser slurry fraction (1602) to the coarse slurry feeding arrangement (1200), and to feed the finer slurry fraction (1603) to the fine slurry feeding arrangement.
