Design of Flotation Cells and Circuits
Until only a few years ago mechanical flotation machine capacity was limited to eight to 15 tons of ore per running foot per 24 hours, and this meant that a "small" 10,000 TPD mill needed in the neighborhood of 150 rougher cells, while a 30,000-ton mill would need about 500 rougher cells.
Compare Flotation Machines Types
In the 1950s, the opinion was often expressed that the mechanically-agitated machine forms the best rougher and a pneumatic machine the best cleaner, the reason being that the former type has come to be regarded as one that yields a heavily-mineralized froth, which, though giving a good recovery of the minerals, is likely to be of low grade …
