Ultrafine grinding now commonly employs stirred mills which are more efficient than conventional tumbling mills for this duty (Chapter 7). Due to the high intensity of ultrafine grinding, inert grinding media is often used to prevent release of depressant iron oxy-hydroxyl complexes.

The sample was dried at a low temperature for two days. Then it was crushed in stages using a jaw crusher and simultaneously screened with a 50 mesh sieve. The resulting coarse fraction was further ground in a roller mill to a minus 50 mesh size. Thereafter, the mono-dispersed feed sizes required were prepared from the minus 50 mesh material.

Ultrafine grinding (UFG) was proposed as a pretreatment method prior to cyanide leaching of old plant tailings of a refractory silver ore. Direct cyanidation of the as-received tailings (d80: 100 µm) led to a low silver extraction of only ≤43% over 24 h. A size-based diagnostic study has demonstrated that the refractoriness of the tailings is essentially physical in character.
