Technical Report: Design and Evaluation of Tailings Dams

Design, and Analysis of Tailings Dams (BiTech Publishers Ltd 1990) This is particularly true of certain concepts and organizational emphases, as well as many of the tables and A number of current and planned tailings facilities in the Athabasca oil sands region are located over large meltwater channel deposits This paper outlines key design and Design of Tailings Dams on Large Pleistocene Channel Deposits

Using Geomembrane Liners to Reduce Seepage through the Base

tailings ponds are located within peatland areas, in valleys, or on hillsides worldwide The objective is to utilize natural soil layers with low water permeability (such as peat and Tailings dams retain the waste byproducts of mining operations and are among the world’s largest engineered structures Recent tailings dam failures highlight Advanced monitoring of tailings dam performance using seismic

Later, in July 2016, the stockpiling of tailings was stopped and the tailings pond was closed More information about Dam I can be found in Report of the Expert Tailings ponds in operation (a) and after closure in August 2000 (b) A pumpandtreat system is currently being used to treat the contaminated groundwater and thereby Tailings Pond an overview ScienceDirect Topics

Planning the Dewatering of a Tailings Storage Facility

The mining industry produces several thousand million tonnes of waste a year, which the same order of magnitude as that of fundamental Earthshaping geological processes (Förstner 1999; Fyfe 1981)Part of this volume is frequently placed in tailings storage facilities (TSFs), which can fail if there is not an adequate design to ensure posal of bauxite tailings generated in aluminum works on purposebuilt disposal sites According to the literature and reports, various examples of planned or built geomembranelined tailings storage facilities can be found around the world (Table 1) Table 1 Use of geomembranes in tailings storage facility (TSF) ponds around the worldUsing Geomembrane Liners to Reduce Seepage through the Base of Tailings

Tailings

In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) of an ore Tailings are different from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processedIn 1994, the Merriespruit tailings dam in South Africa failed, releasing 600,000 m 3 of tailings and 90,000 m 3 of tailings water [81, 117–119]The tailings dam broke after a few hours of thundershowers It is worth mentioning that this tailings pond is basically an upstream structure with less freeboard length and less reservoir areaA Comprehensive Review on Reasons for Tailings Dam Failures

Tailings Ponds 101 Oil Sands Magazine

Tailings ponds are massive earth structures used to store coarse and fine solids contained in the oil sands deposit and recover water back to the main processing plant These ponds are temporary storage facilities and need to be reclaimed when no longer in useFine solids from tailings streams tend to trap large volumes of water, A method of storing the slurry is in tailings ponds Dependent on the design of the pond size will determine its volume, this construction may or may not include the use of a tailings damWhat are Tailing Ponds?

Design and Construction of a Tailings Dam over an Ancient Tailings

La Parrilla is a tungsten and tin mine located in western Spain The tailings facility has a total capacity for 3 Mm3 and will be executed in four different phases The main constraint for the design and construction of the tailings dam is that it has been constructed over an existing one from the 1980s The construction activities involved Later, in July 2016, the stockpiling of tailings was stopped and the tailings pond was closed More information about Dam I can be found in Report of the Expert Panel on the Technical Causes ofPropagation network of tailings dam failure risk and the

Process effluents and mine tailings: sources, effects and management

To prevent the discharge of processaffected water of tailings pond to surface water directly, tailings ponds were first introduced to store the residue before discharge or reuse Generally, mine tailings are disposed by different methods such as drystacking of thickened tailings on land, backfilling into abandoned openpit mines or The tailings accumulation dam is above the 1635 m elevation of the dam crest at the beginning of the tailings pond The dam slope has a total of 4 terraces at elevations of 1735, 1835, 1935, and 2035 m, and the mound width is 5 m, with a slope ratio of 1:45, as shown in Figure 5 FIGURE 5 FIGURE 5Frontiers Numerical Simulation on the Evolution of Tailings Pond

Sustainability Free FullText Stability Analysis of the

Tailings dams are special constructions that are part of a complex of works related to the installations for preparing mining masses These constructions play a role in the mechanical treatment of In this publication, a tailings management facility (TMF) is intended to encompass the whole set of structures required for the handling of tailings including the tailings storage facility, tailings dam(s), tailings impoundment, clarification ponds, delivery pipelines, etc Tailings are the finegrained waste material remaining after the metals andSafety guidelines and good practices for tailings management

Appendix E Tailings Management Plan Mt Todd Gold Mine

The Tailings Management Plan (TMP) has been prepared to highlight potential risks associated with management of tailings, through the design, operations, closure and decommissioning of the tailings storage facilities, and provide strategies to eliminate or mitigate these risks to acceptable levels 12 Tailings Management GuidelinesTailings management is typically easier, at least physically, in dry climates, where advantage can be taken of desiccation (that is, drying by exposure to the wind and sun) to naturally dewater, increase the density of the tailings and strengthen the tailings However, on desiccation in a dry climate, sulphidicMANAGEMENT OF TAILINGS: PAST, PRESENT AND FUTURE

Solution and Stability Analysis of Sliding Surface of Tailings Pond

In the case of rainstorm, instability accidents in tailings ponds occur frequently, but there is no reliable calculation method for the stability calculation of tailings ponds At the same time, there are problems of fuzzy hydrological boundaries and randomness of geotechnical parameters in the stability analysis of tailings ponds, which Tailings ponds are one of the methods used to store tailings, the waste material left over from ore extraction processes Tailings are often mixed with water to create a slurry, which is easier to transport One method of storing the slurry is in tailings ponds (Figure 1) Depending on the design of the pond, this may or may not also include the use of a Tailings pond Energy Education

Flat Ground Tailings Pond This is a tailings pond built on flat ground and surrounded by dams on all four sides (Fig 3)Its characteristics are as follows: There is no water collection from the mountain slope, watercollecting area is small, flood discharge structure is quite simple, the tailings dam is very long, embankment requires large work The impact of tailings pond dam failure on downstream facilities was analyzed, producing the following conclusions: (1) Five minutes after dam breakage, the tailingswater mixture flow will have flooded the downstream highspeed railway facilities and drain opening, of which the scope of influence is longer than 1 kmThe Influence of the Instantaneous Collapse of Tailings Pond

Tailings Management Newmont

Newmont produces more than 100 million metric tons of tailings each year, the majority of which are deposited in engineered tailings storage facilities (TSFs) constructed above ground Tailings management is incorporated into Newmont's Sustainability and Stakeholder Engagement Policy and is supported by our standards and guidelinesIn order to study the effect of the physical properties of tailings on the concentration of tailing slurry underflow, the median particle size, control particle size, and density of the tailings of 9 typical mines were measured Besides, static settlement test and dynamic thickening test of the tailing slurry of these 9 mines were separately conducted Study on the Relation between Tailing Particle Size and Hindawi
