  • Tailings

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.

Dry disposal of tailings is possible but is expensive because of the cost of dewatering the tailings before stacking.7 Dry stacking is a relatively new approach that has been used for higher value ores such as those at copper and gold mines. Gogebic Taconite has suggested that dry stacking may be proposed for use in the Penokee Range

    IntroductionBauxite ResidueDatabase of Dry Stack Facilities in OperationDewatering tailings to higher degrees than paste produces a filtered wet (saturated) and dry (unsaturated) cake that can no longer be transported by pipeline due to its low moisture content. These filtered tailings are normally transported by conveyor or truck, deposited, spread and compacted to form an unsaturated tailings deposit (Davies and Rice 2001). This type of tailings storage produces a stable deposit usually requiring no rSee more on tailingsfoLive Chat
  • Mine Tailings Disposal Methods

    In the past, mill tailings have been discharged onto hillsides or directly into lakes or streams. These practices are now prohibited by state and federal laws. Today, the universal disposal method for tailings is the tailing pond. Tailings are slurried with water and pumped to tailing ponds for settling.

    Surface stacking is the disposal of tailings on the surface of the ground. As a non settling, non segregating suspension of solids, minimal water is released into the impoundment and the stacked tailings dries significantly faster than conventional ponds where fines (slimes) segregate and can seal the surface of the deposit, preventing drying.
