Flotation Circuit Troubleshooting

Flotation Circuits Diagrams - Mineral Processing & Metallurgy

Since several types of flotation circuits can generally be employed in conjunction with the various processes for the flotation of different classes of minerals, an outline of the standard circuits in common use is best given before the processes to which they are applicable are described. The flow sheets illustrating them are diagrammatic, but, in cases where the circuit includes two or more ...

Some results for floatation and flotation with various related_terms are below. M = millions of hits. k = 1000's of hits. e.g. "Australia 420 k / 10.9 M" = 420,000 hits for floatation and Australia, 2.29 million hits for Australia and flotation. Very obviously this method has methodological deficiencies, but it is also demonstrably useful.
