Flotation - Mineral Processing & Metallurgy

The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners. In this case the cells are run in series, the primary cells treating the original feed and the secondary cells re-treating only the slime from the primary tailing after the sand has been removed.
