Flotation | ore dressing | Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

Froth flotation - Wikipedia

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
