The best PVC separation (90% recovery) from the other three plastics was accomplished through flotation at 40 °C at 200 and 240 rpm in a small (0.35 L) and medium (3.0 L) glass flotation cells, respectively. Ozonation was conducted for 10 min by introducing ozone gas (90–150 mg-O 3 L −1) at 50 mL min −1 flow rate.

However, flotation separation deteriorates with low efficiency and low selectivity when treating fine (< circa 20 μm) and ultrafine (< circa 5 μm) particles. Particularly, fine hydrophilic particles affect value mineral recovery and froth product grade by attaching indiscriminately to value minerals, increasing pulp viscosity, and entering ...

Dolomite, a prominent calcium-bearing gangue mineral found in carbonate-type zinc oxide ores, poses a significant challenge for effective flotation separation alongside smithsonite due to their highly similar surface properties.
