Theoretical and engineering aspects of slimes-dam construction

In these cases it is The literature has reported that there are 18000 tailings dams across the globe, out of which approximately 3500 are active.

The stability of slimes dams in the gold mining industry
Slimes dam problems are divided into three types : surface erosion, seepage problems and slide failures. The mechanism of each type of failure has been studied and possible The typical slimes dams serving these mines each occupy a plan area of 50 ha, rise to an average height of 15 to 20 m, wall, and, when complete, contain about 25 million tonnes Slimes disposalatSouthAfrican goldmines

referred to as “mine slimes.” The traditional approach to managing underground slimes is a costly and time-consuming process. It involves allowing the solids to settle to the bottom Tailings dams are retention structures formed by earth materials whose main goal is the storage of mining waste resulting from the mineral benefit process in mining industry. The material stored, called “tailings”, is usually deposited in an aqueous slurry compound, generally called tailing slimes, whose solid particles are made up of silty orAnalysis and Seismic Design of Tailings Dams and Liquefaction

Tailings Dams Geoengineer
Tailings Dams. Tailigns dams are embankment dams constructed to contain and store waste (tailings) of mines. During mining, in order to separate the mineral or metal from the rock, mechanical and chemical processes are used to grind up rock into sand. The great amount of wastewater that is being mixed up with sand and chemicals is referred toclosure for both existing and new mining landforms. 2. OVERVIEW OF CURRENT PRACTICE Worldwide, many mines have one or more active or inactive tailings facilities. Each tailings facility is a mining landform that is already part of the permanent landscape, and which will require reclamation as part of mining’s commitment to be a temporaryCHAPTER VIII CLOSURE AND RECLAMATION Global Tailings Review

How to dewater tailings slurries with slimes and ultra-fines
From these conversations, my understanding is that a slurry with a d 50 of <10µm micron, and with a P 80 of 45µm, would be considered a slimes stream. It often contains ultra-fine particles of the parent rock (e.g. quartz) and silts. It is also frequently associated with clays (aluminosilicates) such as kaolinite, smectite and illite.You've already forked 2023 0 Code Issues Pull Requests Packages Projects Releases Wiki Activity2023/sbm remining coal slimes.md at master 2023 Codeberg

Minister Mantashe concerned about Free State slime dams
Wednesday, September 14, 2022. Minister of Mineral Resources and Energy, Gwede Mantashe, says he believes that a 2007 judgement essentially declaring that slime dams do not fall under the jurisdiction of the department is creating a risk for disasters such as the one seen in Jagersfontein to occur.

The hidden risks of tailings dams NS Energy
The hidden risks of tailings dams. Mining. By Andrea Valentino 21 Mar 2022. Tailings dams are a central part of mining across the world. Yet their inexpensiveness and versatility also come with dangers, especially when it comes to landslides. InSAR technology is designed to detect landslides. They can also take photos Diversified mining and marketing company Glencore is auditing 140 slimes dams, 65 of them active and 75 of them closed. The company has been undertaking detailed assessments and audits of all material tailings storage facilities (TSFs) over the past three years, after accumulating a TSF significant asset footprint through mergers and lining of mining slimes dams

Slimes-dam construction in the gold mines of the Anglo
The average slimes dam compacts at 0,625 m3 per tonne and contains 10 per cent moisture. At 0,625 m3 per tonne, the slime would become saturated at 20 per cent moisture. For example, a slimes dam 15 m high constructed on 85 ha of ground would contain nearly 18 million tonne of solids at 10 per cent moisture, and a slimes dam 35 m high con-engineering design of tailings dams in other mining industry sectors, for both stability and environmental performance. For instance, experience gained with leach pad liners is being transferred to linings for tailings ponds, and the use of synthetic lining materials is growing (although use of liners is still far from being the industry norm).Technical Report: Design and Evaluation of Tailings Dams US

South Africa mine dam collapse highlights patchy regulation
Mining groups expected to comply with global standard next year. Sept 23 (Reuters) The collapse of a tailings dam in South Africa earlier this month has put the spotlight on the need for bindingStormwater that runs off the outer tailings slopes is considered contaminated water which, if allowed to seep into the in-situ soils, would defeat the purpose of lining the dam in the first place. The approach taken for this project was to combine the attenuation function of the catchment paddocks and the conveyance function of the solution trench into one system Journal of the Southern African Institute of Mining and Metallurgy

Process Water Management and Seepage Control in Tailings
In the past thirty years many mining projects in Chile and Peru have used: (i) polymeric geomembranes and (ii) design-and-build cutoff trenches, plastic concrete slurry walls, and grout curtain systems to control seepage at tailings storage facilities (TSFs). Geosynthetics are a viable alternative at a TSF dam for clay cores or impermeable interest in dams in Australia, including many mining companies and professionals working in the mining industry.

The stability of slimes dams in the gold mining industry
The stability of'slimes dams in the gold mining industry— G. ir. Donaldson. Samples of slimes and crust from a large number of dams were analysed and it was found that the important factor affecting crust formation was the amount of iron pyrites present1 in the slimes, as the crusts are formed by products of decom position of the pyrites.
