Froth flotation: a quick overview - European Training Network

Froth flotation represents the most versatile separation method in mineral processing. It takes advantage of the different surface minerals properties to selectively separate more hydrophobic minerals from less ones towards interactions with air bubbles. Flotation has been initially developed to treat the sulfide minerals of copper, lead, and zinc.

A contact angle near 90° is sufficient for effective froth flotation in most cases.

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].

Froth flotation is used to raise the low mineral concentrations in ores to concentrations that can be more economically processed. A concentration of 25–30% is suitable for economical smelting of copper.
