Flotation
Flotation is a method of separating heterogeneous solid and liquid mixtures . For this, air bubbles are inserted in the liquid, in which one of the elements adheres and ends up separating from the other element in which it was mixed. The fact that an element adheres to the bubbles happens due to a hydrophobic interaction (hydro, […]

Two-Liquid Flotation for Separating Mixtures of Ultra-Fine …
This paper reviews two separation methods applying two-step two-liquid flotation for recovering ultra-fine rare earth fluorescent powders (i.e., red, green, and blue). The paper aims to extract the science behind separation by two-liquid flotation, and to provide resulting engineering tips for material recycling. Two-liquid flotation, also called liquid-liquid extraction, involves two solvents ...
