Froth flotation is a versatile and widely used particle separation process. As the flotation rate constant is a function of particles size, however, at a typical flotation residence time the recovery of particles in different size fractions varies widely, with high flotation performance being limited to a narrow particles size range (e.g., 20–100 µm for base metals, and 38–200 …

Flotation is the most widely used method for the concentration of fine-grained minerals. It takes advantage of the different physicochemical surface properties of minerals—in particular, their wettability, which can be a natural property or one artificially changed by chemical reagents. By altering the hydrophobic (water-repelling) or hydrophilic (water-attracting) conditions of their ...

Froth flotation is the separation process whereby small mineral particles are captured by air bubbles and removed from the slurry as a froth. Consequently, two broad types of reagents are necessary in flotation: reagents to control the wettability of mineral particles and reagents to control ing or frothing.
