ABSTRACT A considerable diference exists between the flotation separation of artificial minerals and real low- grade ores processing where selectivity would be the main issue. Nanobubble-assisted (NB) flota-tion investigations have been mostly examined with pure materials and a narrow particle size range, less on complex sulfide ores.
