  • Ro-Star™ Vertical High Intensity Ultra-fine Grinding Mill

    Due to limited competition in this ultra-fine grinding mill market these mills are generally very expensive and thus increasing the overall capital cost of such projects. The Ro-Star mill development originates from MMS’s requirement to grind refractory gold concentrates to very fine sizes as part of its Leachox™ process. As such MMS has gained valuable experience in investigating and

  • Ultrafine Grinding an overview ScienceDirect Topics

    Ultra-fine grinding (P 80 ≤ 10 μm) 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; Gonzalez-Anaya et al., 2011), as is practiced at Kalgoorlie Consolidated Gold Mines, a joint venture between Barrick and Newmont.
