What are Tailings and TSFs? | BHP

The principal difference between tailings dams and conventional water dams is that tailings dams are dynamic structures that grow over the life of the mine to accommodate increased tailings Tailings dams, and particularly ‘upstream’ dams (see types of dams below), often rely on the strength of hydraulically placed tailings that are variable in strength due to mine

Slope failure mechanisms in hydraulically placed coarse

Coarse sand tailings deposited during the mineral sands mining process can often contain varying quantities of clay and silt sized particles referred to as “slimes” When placed hydraulically, these slimes can become trapped, resulting in pockets or lenses of sandslime mixtures within the quartz sand tailings Extensive mineral sands deposits exist in Western
