Development of ultrafine grinding at Kalgoorlie ...

2003-11-1 · In February 2001, Kalgoorlie Consolidated Gold Mines (KCGM) commissioned its first full-scale ultrafine grinding (UFG) plant to supplement its existing roaster-concentrate treatment capacity. The process involves the fine grinding of refractory pyritic concentrate to 10 μm followed by direct cyanide leaching for gold recovery. By this means, gold can be economically extracted from the ...

GOLD RECOVERY The golden age - min-eng

2015-4-24 · “Ultra Fine Grinding (UFG) uses Isamill technology to grind the ore to sub 10 microns and then leach the ore. The risks are low but power costs and suitable low cost grinding media are important. This is particularly applicable to particulate refractory gold ores. An example of the use of this is by Kalgoorlie Consolidated Gold Mines.
