A theoretical analysis of principal guidelines to intensify the flotation wastewater treatment has evidenced the feasibility of increasing pressure flotation efficiency via thin-layer settling (lamella flotation) and secondary saturation of the flotation cell with a water-air mixture containing increased hydraulic size air bubbles floating in ...
The ability to operate at gas and wash water fluxes above what is traditionally possible with any other existing flotation equipment sets this technology apart and allows for production of superior quality flotation product at elevated recovery.
Air rate and froth depth are the most commonly adjusted levers in PGM flotation plants. The optimisation of these levers on each flotation cell has traditionally been done by varying either air rate at a fixed froth depth or vice versa.
Efficient and robust design features a high-turbulence bubble/particle contact chamber that feeds an external froth separation and recovery chamber.
