Froth flotation - Wikipedia

The froth is removed from the cell, producing a concentrate ("con") of the target mineral. Frothing agents, known as frothers, may be introduced to the pulp to promote the formation of a stable froth on top of the flotation cell. The minerals that do not float into the froth are referred to as the flotation tailings or flotation tails.
