Deposition Methods of Tailings

IntroductionDeposition TechniquesSubaerialSubaqueousSpigotsSingle PointFor conventional storage the tailings are generally discharged from spigots/outfalls located along the embankment(s) of the facility. For surface thickened and paste storage the tailings are generally discharged from a central location either through risers or from point sources that are raised over the life of the facility.

Mine Tailings: The Cornerstone of Safe Mining Operations

2024/3/29 One of the most common methods for managing mine tailings is the construction of tailings ponds or tailings storage facilities (TSFs). These large-scale repositories serve as containment areas for the collected material, allowing for the settling of solid particles and the retention of water before eventual disposal or treatment.

Tailingsfo Surface Tailings Containment

Co-disposal is a mixing of tailings and coarse mine waste to produce a single waste stream (Martin, Davies et al. 2002) or by co-placement seperating the two waste streams in a single storage facility. This method of tailings storage is most suitable to the backfilling of voids (underground and open pit), the covering of conventional tailings ...

Tailings Fact Sheet

impoundments are the most commonly used method for tailings storage facilities (TSFs). The raised impoundment design methods for TSFs are typically downstream, upstream or centerline. This designates the direction in which the embankment crest moves in relation to the starter dam (dyke) and the base of the embankment.
