Gravity concentration has been applied to particles nominally from 0.1 to 1.0 mm (with some extension beyond this range), leaving the range from 0.01 to 0.1 mm as the natural preserve of flotation. The challenge for gravity concentration is increasingly developing a focus on the finer size range below 0.1 mm. This is most evident in mineral ...
