Frequently, tailings are cyclone classified before deposition. Coarse sands are used to build up the tailing dam, while the slimes are deposited inside the pond. The slimes provide some degree of sealing, which slows the rate of seepage from the pond. Many ponds are trenched at the base of the dam or have adjacent toe ponds to collect seepage.

These safety guidelines and good practices for tailings management facilities promote good practices that will help avoid accidents at such facilities and minimize the effects of any accidents that should still occur. By using these guidelines, Governments and industry are fostering the protection of the environment and human welfare in our region.
Retreatment of Residues and Waste Rock D.W. Bosch 12.1 Introduction From the commencement of gold mining on the Witwatersrand in 1887 up to 1984, a total of approximately 4,2 billion tons of gold ore has been milled Residues contained in sand dumps and in slimes dams consist essentially of
Tailings dams were also not needed in most cases, as operations were relatively small compared to modern operations today. Due to the development in processing methods and mine equipment, operations are now able to mine deposits well into lower grade
A tailings dam is typically an earth fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive.Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth
As there is seldom enough ground available on which the tailing of a flotation plant can be run to waste without being stacked, it is usual to impound it in some form of dam where the solids can be deposited and the water decanted off for return to the plant. It is generally advisable to recover as much of the water as possible in order not only to save the expense of obtaining a fresh supply
Coal from slimes. This service creates value from of an environmental liability. Our unique Eco Plant174; process has enabled us to recover export quality coal from slimes dams/thickener underflows and dewater to meet moisture requirements.

Abstract Gauteng is the most industrialized province in South Africa, and one of the most industrialized
Is anyone aware of any Geometallurgical Modelling on Tailings Dams and tailings slimes being done or that have been done in the past? I would like to get in touch with people involved in such studies.We have just commenced on a project of this kind. Within the next two years we will s
The method suffers from the disadvantage that the dam wall is built on the top of previously deposited unconsolidated slimes retained behind the wall. There is a limiting height to which this type of dam can be built before failure occurs and the tailings flow out and, because of this, the upstream method of construction is now less commonly used.

Tailings dams are embankments constructed from waste rock to impound the tailings generated in a mine processing plant. Tailings are the by product of extractive industries and are mixtures of crushed rock and processing fluids that remain after the extraction of economic materials from the mine resource (Kossoff et al, 2014).

Recovery of iron values from slimes results in economic benefit by utilisation of waste as a resource and minimizes the land requirement, surface degradation, ground water pollution, destruction of forests. These slimes after beneficiation are agglomerated (Pelletisation) and
The iron ore slimes sample used in this work was collected at 21 points (the depth varied from 0.36 to 1.18 m) in the dam tailings of Fund227;o at the Samarco Mining site which collapsed on November 5th, 2015. In this dam, the slimes from the desliming operation of
VortexIS is arguably the only cost effective solution for processing fly ash from ash pond and slime dams. As these ponds/dams become an environmental risk over time our clients now have a solution that simultaneously beneficiates the ash to an ultra fine
The underground mining has resulted in the requirement for slimes dams (West Dam, Middle Dam and East Dam) within the mine premises. Koffiefontein is one of the worlds top kimberlite mines by average value per carat. The mine produces high value diamonds, a regular proportion of which are beautiful white diamonds between 5 and 30 carats in size.

I have been involved in quite a few projects evaluating slimes dams. The simplest and cheapest way to sample fine material in a slimes dam or sand dump is with an auger fitted with a sleeve to hold the sample. This is a small rig, hand portable, often on a frame of some sort and with a
