Mine Tailings an overview ScienceDirect Topics

Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.

Grinding control: The best way to avoid tailings problems is to not generate excessive fines. While fine grinding is favoured to liberate values, over-grinding leads to physical limitations on dewatering and should be avoided at all costs.
