Scheffel (2017) recommends that the ore should not have more than 10% to 14% -150 μm material and not more than 40% -5 mm material for it to be suitable for heap leaching. The change in bulk density exerted by the weight of the ore at the bottom of a pile, stacked to a specified height, is commonly measured.
