Energy Use of Fine Grinding in Mineral Processing ...

At Mt. Isa Mines, a GIS mill fed with material of F80 approximately 50 μm lowered the P80 size by only 5 to 10 μm, at the same time producing a large amount of fines. Similarly, in ball mills, it is known that grinding finer than approximately 40 μ m will result in overgrinding of fines as well as high media consumption.
