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 [8].

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.

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.

The existing regulatory approved method of closure included placement of a minimum of two feet of topsoil over the tailings.

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.
