Hydrodynamic and gas dispersion parameters, obtained from industrial flotation cells on South African Platinum concentrators, are reviewed in this paper. Hydrodynamic results show that power intensities are slightly higher than those typically observed in industrial flotation cells while impeller tip speeds and Froude numbers are …

Platinum group metals (PGMs) are primarily used in automotive exhaust catalysts (autocatalysits). Spent autocatalysts are the most important secondary resource for PGMs. However, transporting autocatalyst scraps and recovering PGMs from the scraps are costly and time-consuming, owing to the low PGM content in spent autocatalysts. …

Cawthorn [1] has estimated that South Africa has reserves and resources of platinum group elements (PGEs) of about 85,000 metric tons. In Russia, Norilsk alone has Pt and Pd reserves of about 2500 metric tons [2]. Platinum group metals or elements commonly refer to ruthenium, rhodium, palladium, osmium, iridium, and platinum and will be referred to

The BIC is the largest known repository of PGE global resources, primarily in the Upper Group 2 (UG2), Merensky Reef, Platreef, and the BIC satellite intrusion, Nkomati Nickel Deposit (Blengini et al., 2020; USGS 2022).South Africa remains the world's top producer of platinum and the second-largest producer of palladium (McFadzean et al., …

This study investigated the effect of energy/power input on the flotation of a platinum ore in a pilot-scale oscillating grid flotation cell. From this study one may conclude that energy/power input has a significant effect on the flotation rate which is strongly dependent on the particle and bubble size. For larger bubbles, increasing …

Platinum group elements (PGE) are recovered by flotation from the Merensky reef in the Bushveld Complex, South Africa. The reef contains approximately 1% sulphide minerals in the form of ...
