Froth flotation is a method of mineral separation which relies on the different chemistry between minerals and gangue. Energy savings are possible through using more advanced froth flotation technologies and control engineering. Technologies such as the Jameson Cell produce smaller bubbles more consistently than previous flotation cells.
