Froth flotation is the single most important unit operation in mineral processing. One can selectively float any mineral from associated minerals in an ore provided an appropriate reagent is designed to make the given mineral surface, selectively and sufficiently hydrophobic so that it can attach to bubbles in the flotation cell and thus …

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.

Froth flotation, often referred to as simply "flotation," is a highly effective mineral separation process that capitalizes on the inherent differences in surface properties among various minerals. This process begins with ore preparation, where the ore is crushed and ground into fine particles. It is then mixed with water and treated with ...
