In crushing an ore for amalgamation, the aim should be to crush just fine enough to liberate the gold from its matrix of quartz or other mineral, that these golden grains or flakes may be exposed to and caught by the aid of mercury. Crushing too coarse will result in the gold not being liberated, but still enclosed in the gangue rock so that the mercury is unable to reach it
