Large production mills operate at relatively low vibrational frequencies and high amplitude (for example, 1000 to 1500 rpm and up to 12 mm, or 0.48 in.). The vibratory ball mill is an excellent means of producing solid-state alloyed and dispersion-strengthened metals in amounts up to 4.5 kg (10 lb) or more, depending on the apparent density of ...

The efficiency of the process is influenced by particle surface changes resulting from the reaction of the grinding media and dissolved gases. In this way, gold recovery is governed by oxidation-reduction reactions in the slurry, although there is some doubt as to whether it is the oxidizing conditions or the oxidant which affect both processes.
