The energy requirements of your grinding circuit are an important factor in determining project economics. The grindability of your orebody affects how much energy is required, especially if ultra-fine grinding is necessary.

SGS's comminution services include ultra-fine grinding testing using a four-liter Isamill. The test generates a signature plot which is used to determine the energy required to grind a sample to a few microns.

SGS's team of experienced engineers use the Isamill in combination with other bench-scale tests and circuit simulation. Our experience indicates that the most robust results are obtained when more than one approach to grinding circuit testing and design is used.
