Fundamentals and applications of nanobubbles: A review
Nanobubble production and exploitation gain exponentially increasing attention the past two decades. In fact, nanobubble or fine bubble technology comprises many sectors and its ever growing market share, in 2016, was forecasted to reach €145 M in EU until 2030 (Fig. 1).A recent global report of 2022 refers to multi-billion dollar market with wide spread of applications …

Flotation of gold and gold-bearing ores
Gold particles in an ore deposit will vary in size from large nuggets to particles locked in the crystal lattice of sulfide minerals. These sulfide minerals are referred to as gold carrier minerals and contain trace to minor amounts of gold (Taggart, 1927; Chryssoulis and Cabri, 1990).Often it is found that gold ores are refractory due to the small size of the gold …

Size by Size Particle Size and Flotation Recovery
The straight pneumatic machine showed a higher recovery of the finer fractions as evidently this product was carried over mechanically with the froth and with low concentrating efficiency. The fine mineral recovered had no economic value since the greater percentage of semi-collodial gangue matter in the concentrate offset the value of the mineral recovered.
