The 'grinding circuit' is therefore used to slurry the ore, and may include a SAG mill or ball mill. Ores are typically ground to 100–250 μm prior to the whole ore being leached. The effect of declining ore grades on embodied energy for pressure acid leaching of nickel laterite ore is shown in Fig. 10 and Table 3, Table 4.
