A Guide to the Management of Tailings Facilities

Tailings facilities are site-specific complex systems that have unique environmental and physical characteristics. They pose a significant business risk that must be effectively managed for the long term. The mining industry has the technology and resources to safely site, design, construct, operate, decommission and close tailings facilities, but

Tailings Fact Sheet

Where tailings slurry is deposited in the facility, the water separates from the heavier sand and silt particles and collects to form a decant/reclaim pond on the surface of the impoundment. The tailings pond water is then recycled back into the milling process for reuse. The tailings are contained within the facility

Safety guidelines and good practices for tailings

A tailings storage facility is a facility used to contain tailings. This can include a tailings dam (impoundment and pond), decant structures and spillways. A tailings storage facility can also be open pits, dry stacking, lakes or underground storages. A tailings dam is a tailings embankment or a tailings disposal dam. The term

To some degree, the design of the retaining embankment is independent of the type of impoundment layout. The only considerations are costs associated with starter dyke and subsequent raised construction, the volume of material required to establish a particular height, the tailings properties and the water storage requirements of the facility.
