### Geometallurgy - Wikipedia

The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior [18] The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant
