Tailings dewatering Weir Group

2019-11-18  The foremost 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. This can also minimise power requirements.

Tailing Disposal an overview ScienceDirect Topics

David John Williams, in Ground Improvement Case Histories, 2015. 2.4 Beaching behavior of mine tailings. The predominant method of tailings disposal is by pumping and sub-aerial deposition of an aqueous slurry (typically at 30–45% initial solids concentration by mass and an initial gravimetric moisture content, w, of 233–122%) to a surface TSF.The tailings may be discharged from a single

This way of thinking leads to tailings being stored as a slurry in surface facilities that are often initially too small, leading to high rates of rise, and creating wet and soft tailings deposits that store excessive amounts of

High density slurry and paste tailings, transport systems

2009-8-26  high density tailings and a paste slurry. From a pipeline flow perspective, it is necessary to understand the changes in flow behaviour as solids concentration increases and it is not always necessary to define the slurry as thickened or a paste tailings. The same applies to the preparation and disposal requirements. It is nonetheless, important to

Rheology for thickened tailings and paste history, state

The current knowledge in the area of concentrated slurry systems is much greater than in the 1970s and this has facilitated increased implementation of thickened tailings and paste systems. Rheology is one area that has made a very significant contribution, however, even at the early Paste and Thickened Tailings Seminars

Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are 3.23 and 3.08, respectively, which are consistent with those of metal tailings but much higher than those of natural soils.

Tailings.info Deposition Methods of Tailings

2021-1-4  Tailings are discharged onto a portion of the gently sloping beach creating braided flows towards the supernatant pond. Upon completion of this layer the discharge point is moved to another section of the beach leaving the newly deposited layer to drain, bleed and dry.

Tailings.info The website focused at tailings related

2021-1-4  The word tailings is sometimes applied to include coarse mine waste. For this website the term tailings refers to the slurry waste output from the processing plant. The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal.

Pumping system design challenges for high-density iron

Fine iron ore tailings slurry is commonly deposited in tailings storage facilities across the Pilbara region of Western Australia. Many of these mines process ore from a combination of deposits such as Bedded Iron Deposits (BID), Channel Iron Deposits (CID) and Detrital Iron Deposits (DID), mixing the feed to obtain the product under contract.

Tailings Earthworks

Tailings, most often in the form of a wet slurry, are conventionally stored above-ground behind earthen dams. There is no comprehensive global registry of tailings dams. It is estimated there are around 18,000 dams, 3,500 of which are active. However, that number may be much higher. For example, China alone has more than 12,000 tailings dams.

The IPTSF will comprise both the Rav8 underground-workings, and the Rav8 Pit. It is proposed to initially discharge process-tailings into the underground-workings, so that the majority of the void-spaces are filled.
