How Particle Size Affects Flotation

There is a marked particle size effect on both R and K. Table V gives an example of increasingly finer grinds in flotation with a different sulfide ore blend. Within the times of grind indicated, there is a tendency for both the over-all R and K values to increase with finer grind [see also Table III of reference]. This trend continues until sufficient fine material is produced (e.g., note the ...
