Fig. 16 shows one of the two MIG M10000 (Midstream Inert Grinding) mills as well as a UFG M3000 (Ultra Fine Grinding) mill, working as regrinding mills for concentrate. The IsaMills TM have been in operation there since March 2009. The maintenance cycles for these units are longer than 6 months.
Gold grains in Figure 1c are extremely fine, and locked in arsenopyrite. This type of gold may be recovered by ultra-fine grinding followed by cyanidation of the sulfide concentrate, although this is in fact seldom beneficial, as the gold grains are usually finer than the finest practical grind size that can be achieved in commercial mills.
2ZM series of vibration mill is a new type of efficient grinding equipment in grinding fine and super fine powder materials.It is more convenient than conventional rotary grinding machine (efficiency of 2-5 times, reducing energy consumption by 20% - 30%). the machine has various vibration strength,high efficiency,low power consumption, less noise and …
A common pre-treatment method to overcome this type of refractory ore is to increase gold liberation by ultra-fine grinding of the iron sulphides (Ellis and Gao, 2003; Harbort et al., 1998 ...

Ultra- ne grinding of refractory Akoluk Au-Ag ore by stirred mill Geliş (received) 25 Kasım (November) 2009; Kabul (accepted) 05 Ocak (January) 2010 Oktay CELEP (*)
An antimonial refractory gold/silver ore sample obtained from Akoluk (Ordu-Turkey) was used in this work. The ore sample was crushed down to − 4 mm using jaw and rolls crushers, and riffled to obtain 1 kg representative sub-samples.These were then ground in laboratory rod mill at 50% pulp density for 40 min (80% passing size, d 80 = 60 μm) …
The shape characteristics of the ore going into the plant scale ball mill and IsaMill, and coming out of the IsaMill are very similar, and these are close to the shape characteristics of particles in the laboratory feed, as well as progeny from the laboratory stirred mill. Although fine and ultra-fine grinding in the laboratory ball mill led to ...
Ultra fine grinding by using stirred media mills has recently received great interest for treatment of refractory gold ores or plant tailings (Corrans and Angove, 1991;Davey, 2010; Celep et al ...
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

This study investigated ultra-fine coal grinding performance of four low- to moderate-cost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of 5.9 μm from a feed size of 24.4 μm while having a specific energy (SE) input of 309 kWh/ton. Nonetheless, the least …
