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 ...
This paper details the operation of the ultra fine grinding process at KCGM as a non oxidative treatment for the extraction of gold from a refractory ores. 2 Introduction The refractory nature of gold ores is often associated with gold finely disseminated in sulphide minerals, such as pyrite, at conventional grind sizes.
mill. The discharge from the mill is pumped to a cyclone for classification. ... (CUF) for further grinding. Eventually, the ore is ground fine enough (typically in the range of 75-250 µm P 80) and reports to the cyclone overflow. From there, the fine gold particles that have reported to the cyclone overflow, are ... The ultra-fine gold ...
The ultra fine grinding mill can grind the ore material to be 2-20um, is widely used in all kinds ores' concentrate regrinding like gold ore, copper ore, silver ore, lead-zinc ore and other refractory metallic & nonmetallic minerals. Through ultra-fine grinding, the ore is fully dissociated, which creates good conditions for subsequent ...
