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 (d 80: 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.
