Froth flotation -a process where valuable minerals are separated from tailing by inducing them to gather on the surface of a froth layer. This process is based on the ability of certain chemicals to modify the surface properties of the mineral(s). Other chemicals are used to generate the froth and still others are used to adjust the pH.
