Current reclamation of historical uraniferous tailings dams and sand dumps. Gold mines produced more than tailings storage facilities and the rehabilitation of these facilities can be complex and the results misleading if measures only in the short term.

3 Vegetative - covering the surface of the tailings dam with plants, grasses, etc. Vegetative methods are reported to be excellent in terms of effectiveness, need minimal maintenance and are cheaper from cost point of view. 2 Further it is asserted that plant cover on tailings dams is as real as mild steel. typically un-vegetated) gold mine tailings sites become an environmental problem as they are prone to wind dispersion and water erosion (Mendez and Maier, ). Some studies have recommended nutrient supplementation to support plant growth (Schwab et al., ). Bioremediation, on the other hand, creates a vegetation cover that serves toFile Size: KB.

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 Size: 1MB. Investigation into the slimes dams, mine dumps and landfills (residue mine dumps and slimes dams contain very fine particles which are easily inhalated. There is a high chance Randfontein Estates gold mine .
Rock cladding can also be used to stabilize the slope of a mine dump. This seems to be the most practicable solution to these mine. The mine dumps and slimes dams in Gauteng could be a far bigger threat than acid mine drainage (AMD).
They are causing radioactive dust fallout, toxic water pollution and soil contamination Author: Sheree Bega. Terminology. Tailings are also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terra-cone (terrikon).
Examples Sulfide minerals. The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS 2) and Iron(II) sulfide (FeS.
Over emphasis of certain vegetation attributes such as diversity of species, grazing potential etc. while ignoring the function that the vegetation cover has to full-fill (the main function of a vegetative cover on gold tailings is to reduce air pollution (dust) and to reduce water pollution (sediment and salt load).

operation of tailings dams in the gold-mining industry hasbecome of increasing importance inviewofthe enormous tonnages requiring de-position. The annual tonnage cur-rently being deposited asaresult of operations by the Anglo American group ofgoldmines iscalculated at between 25and 26million, and the total area setaside forthis purpose.
Similar successful results were also obtained on a gold mine overburden site. Coal Mine Tailings. In an attempt to rehabilitate an old coal mine tailings dam, (surface area of 23 ha and capacity of million cubic metres) a trial was set up to select the most suitable species for the rehabilitation of this site.
slimes dams soon after placement. In spite of intensive liming, soil acidity would increase. Experiments showed a direct correlation between the amount of residual pyrite in the tailings and the quantity of lime required to ensure sustained vegetative cover.

Soil Stabilization or Rammed Earth has been used for thousands of years as a basic building material.
Soil stabilization from the Ancient Pyramids to the Great Wall of China, soil has provided structural solutions that were principally based on the binding properties of clay soils. water erosion on the tailings and establish a self-sustaining vegetative cover without the use of imported topsoil and long-term maintenance.
The existing regulatory approved method of closure included placement of a minimum of two feet of topsoil over the tailings.
In reality, at least three feet of cover would need to be placed to bridge over theFile Size: KB. A program to alleviate the condition by developing a vegetative cover over the tailings was commenced in The work was successfully carried out and demonstrated that the large area of waste could sustain a permanent cover of paper outlines the experimental work done at Buchans as well as the procedures followed and the.

the concentration of cd remained stable with a concentration of mg/kg. Water and sediment became heavily polluted with high levels of zinc _____ During floods in andcatastrophic contamination of the river occurred when tailings and slimes dams collapsed; inapproximat m 3 of tailings were discharged into the flooded Molonglo River and were subsequently deposited on the river flood plain some 12 km downstream, damaging large areas of.
The water removed from tailings dams can be, and often is, later reused in the mine’s processing cycles. There are two tailings dams at .Striking gold requires some geological and historical soil analysis of an area.
Certain types of soil and rock formations are more likely to be gold-bearing due to environmental and geological processes. Gold is relatively rare, but it occurs in various types of soils and environments, particularly those that have been shifted or compacted by.
