· In addition to the effect of grinding particle size on froth flotation, slurry is also prone to produce slime during the grinding process. Excessive slime will result in the decrease of concentrate grade, affect the froth flotation of coarse grains, consume flotation …
Particles from 1 to 1,500 microns are produced in different sizes: particles below 100 microns, around 400 microns and larger than 800 microns. A grinder can never produce of particles of the same size, but they are more or less accommodated in a few micron ranges. This is called grind distribution.
Comminution is particle size reduction of materials. Comminution may be carried out on either dry materials or slurries. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while
