As shown on Figure 1, the dam crest was at el. 534m and the water level at el. 529.6m at the time of failure. The current water level is about el. 517m, with the slimes surface about 1- 2m below the water level at approximately el. 515m. Thus, virtually all of the impounded water was lost in the failure. In November, 1994 the slimes surface was ...

Technical Report Design And Evaluation Of Tailings Dams
Slimes are often used to line the upstream face of tailings dams (or lifts). Although slimes may offer a low-cost alternative to other materials, they have several disadvantages that are discussed in Vick (1990) and Ritcey (1989). In addition, it is difficult to determine long-term permeabilities of the slimes.
Tailing Disposal Methods and Tailings Dam Construction Design
· Tailings Dam Construction Design. of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.

Hydraulic mining is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.. Hydraulic mining developed from ancient Roman techniques that used water to excavate soft underground deposits.

Geology of Johannesburg, Republic of South Africa ...
Granite and andesite are the remaining aggregate sources. Mining residue deposits in the form of slimes dams and sand dumps are common in many residential and industrial townships of Johannesburg. They pose severe and complex environmental problems such as water and dust pollution as well as long term erosion and slope stability problems.
Process for the treatment of mineral slimes
At present, the slimes are contained in ponds or impounded areas surrounded by earthen dams. There the slimes are allowed to settle by gravity. However, this process takes a number of years, usually over ten, to form a 20% solids concentration.
Gold Mining Exploits and the Legacies of Johannesburg''s ...
The continual extraction of gold and waste products, generated by increasingly deeper mining operations, has created a landscape that is strewn with large mounds of mine waste and slimes dams. Although mining activity adjacent to Johannesburg has ceased, this landscape of extraction awkwardly intercepts the city''s freeways, human settlements ...
Code of practice for small quarries
· Design slimes disposal areas to promote, where possible, rapid drying and consolidation. Minimise storage of slimes in dams wherever possible. Monitor the stability of slimes dams. Control dust from dried slimes. Ensure that slimes are securely fenced and appropriate signs are in place to warn of potential hazards.
Retreatment of Residues and Waste Rock
12.2.1 Sand dumps and slimes dams Residues contained in sand dumps and in slimes dams consist essentially of three different products, namely separate sand and slime and slime from the all-sliming process. In the early days gold was recovered from stamp-milled material by gravi ty concentration only.
PROCESS OF REMOVING WATER FROM SLIMES
The slimes are typically disposed of by discharging them into excavations or, as is perhaps more common, into reservoirs or ponds which are formed by a constructed earthen dam-work. The slimes are allowed to settle by gravity; the water which separates from the slimes during settling is usually recovered from the slimes settling pond for reuse ...
The Aurul S.A. tailings dam failure (Baia Mare, Romania)
The dam failure and its impacts On January 30, 2000, a tailings dam failure at the Aurul S.A. plant in Baia Mare, Romania, resulted in the release of 100,000 m 3 of cyanide-contaminated liquid into the Lapus stream, tributary of the Somes/Szamos, Tisza/Theiss, and Danube Rivers, killing tonnes of fish in these rivers and poisoning the drinking water of more than 2 million people in Hungary.

· The remaining 1% of suspended solids settle in the buffer dams and pipes. One per cent suspended solids, in a flow of 3000 m 3 /day, will fill a 3 500m 3 dam with solids within 10 months, assuming that the specific gravity of the mud is 1,4kg/ m 3. Critical system failures occur when underground dams fill with mud and silt.
· Copper Flotation Process Summary. Flotation of Copper Ores. Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs.

· Tailings dams are used to store water and waste that come as by products from the mining process. It is estimated there are at least 3,500 tailings dams around the world. But as there are around 30,000 industrial mines, the number of tailings dams is likely to be much higher. Tailings dams can be huge in size, as big as lakes, and reach 300 ...

· During production of calibrated (sized) ore, more than 50 % of the generated fines and rejects (Slimes) cannot be directly utilised in iron making due to its unfavourable granulometry, low iron content, high alumina and silica content. Approximately 10–20 % of the process plant input is discarded as slimes into slime ponds/tailing dams. Tailing dams are now considered as a threat due to ...

seepage and leakage). Depending on the percentage of remaining water and solids the tailings can be defined as slurry, paste, filtered or cake (from less to more percentage of solids). Tailings dams are often constructed with readily available materials rather than the concrete used for example in water storage dams.
