Nanobubble assisted flotation separation of complex Pb–Cu–Zn sulfide ore – Assessment of process readiness

A considerable difference exists between the flotation separation of artificial minerals and real low-grade ores processing where selectivity would be main issue. Nanobubble-assisted (NB) investigations have been mostly examined with pure materials a narrow particle size range, less on complex sulfide ores. This study considered NB for Pb-Cu-Zn ore in two different ranges various conditions to assess process readiness. Metallurgical responses (recovery, grade, kinetics, index) were determined, compared conventional tests. Outcomes revealed that an inclusive fraction (−150 µm) could result higher selective than fine (- 38 µm). In contrast, mass recovery kinetics one. general, adding NBs (CB) improve metallurgical responses; however, way generated key. presence frother (NBF) produce water recoveries while decreasing selectivity. setups’ products showed following order Pb-Cu sulfides: NB>NBF>CB. These results opened new approach considering generation when they are going use stages.
