About Tailings Global Tailings Review

Tailings is a common by-product of the process of extracting valuable minerals and metals from mined ore. They usually take the form of a liquid slurry made of fine mineral particles, created as mined ore is crushed, ground and processed. Effective tailings management is integral to the safe and sustainable production of metals and minerals.

Dry Stack Tailings In Cold Regions: Opportunities And

Mine developers and operators are evaluating filtered tailings, also known as dry stack tailings, as an alternative to whole slurry, thickened, and paste tailings. Focus on enhancing physical stability and reducing short- and long-term liability associated with tailings storage facilities has increased, in part due to the failure of the

Tailings Management Using the Weir Mobile Pumphouse Weir

Sep 09, 2020· Pumping stations are a critical element of tailings management, providing the energy needed to drive the downstream processes. Static slurry pumphouses have until now been the norm, but they are costly and present many limitations when considering alternate tailings processing techniques. A new approach to tailings reclamation

Dry Stack Tailings Storage Twin Metals

Dry stacking is the most sustainable method used to store filtered tailings — the silty, sandy material that’s left over once the metals are extracted. In the dry stack method, tailings are placed and compacted in a mound that is concurrently reclaimed with native soil and vegetation.

CSU and partners create mine tailings nexus to improve

The remaining material is a slurry of process water and waste solids called tailings. This slurry often is deposited in a long-term containment facility intended to protect nearby inhabitants and the environment from contamination. Bolstering tailings education at CSU. Too often, tailings storage facilities fail, causing death, environmental

Tailings Retreatment: The Next Revenue Source for the

Tailings deposited into dams are in the form of a slurry. In 1998, a tailings dam failed at the Los Frailes zinc mine in Spain, causing more than one billion gallons of acidic, heavy metal-laden sludge to spill into the surrounding area, eventually making its way into the Guadiamar River. The spill decimated the area, resulting in massive

STATIC LIQUEFACTION IN TAILINGS DAM AND FLOW FAILURE

Mine tailings can be classified as slurry, paste, or cake, according to its final solid/liquid ratio (S:L), which arises from the treatment given to the slurries at the end of the extraction process. Slurry undergoes no treatment, paste is a thickened slurry, and cake is a filtered slurry (see Fig. 1).

The benefits of dewatering tailings with Weir World Pumps

Oct 20, 2020· The most important benefit of dewatering tailings is the reduction of water that needs to be transported from a process plant to a tailings storage facility (TSF). Reduced water content means tailings' slurry volume is decreased, allowing for smaller pipelines and pumping equipment to be used, which can minimise power requirements.

Tailings Management Time for Radical Innovation?

Mar 18, 2019· Tailings dams rank among the largest engineered structures in the world, sometimes reaching up to 300 metres in height. These dams are designed to permanently contain finely ground mineral processing waste, a watery slurry of rock particles that are left behind after mineral extraction and are placed in an impoundment.

Dry Stack Tailings: An Alternative to Conventional

Jun 16, 2020· To reduce the tailings volume further, dewatering technologies have to be employed to remove additional water from thickened tailings slurries before placement in the containment pond. Dewatering technologies can reduce tailings volume an additional 5-10%, but more importantly, sufficient water is removed creating a dry, stackable material.

Tailings Wikipedia

The modern tailings designer has a range of tailings products to choose from depending upon how much water is removed from the slurry prior to discharge. The removal of water not only can create a better storage system in some cases (e.g. dry stacking, see below) but can also assist in water recovery which is a major issue as many mines are in
