Mill (grinding)Wikipedia • The SAG Power Index (SPI®) Test is a measure of the hardness of the ore from a SAG or AG milling perspective. Conducted in a bench-scale SAG mill the SPI® test measures the energy needed to perform a standard size reduction (expressed as an index). The SAG milling of ores with high levels of competency leads to high SAG mill specific power consumption and a high proportion of very fine SAG mill product. In these ores the principal source of fines generation is abrasion of the competent charge in the mill rather than coarser breakage.

### Mineral Concentration Plant and MillingMinera San

Power consumption in a modern mine is extremely high. A processing plant of the size of that of Minera San Cristóbal could supply energy to a small city. Most of this energy is used in the milling circuit that represents 50 of the total consumption. Nevertheless in San Cristóbal the mills are controlled by a system of high-tech sound. Power models in SAGMILLING are all expressed relative to the mill shell for both specific energy consumption (eg. E sag kWh/t) and for mill power draw models (eg. ball mill power prediction for a mill geometry). This relative to the mill shell definition roughly corresponds to the amount of energy that ore consumes given an
