Ultrafine Grinding an overview | ScienceDirect Topics
Ultrafine grinding (P 80 10 m) has been proposed as an alternative to unlock gold from sulfidic refractory ores; however, the cost of size reduction to this level makes it applicable only for concentrates (Corrans and Angove, 1991; GonzalezAnaya et al., 2011), as is practiced at Kalgoorlie Consolidated Gold Mines, a joint venture between Barrick and Newmont.
