Geotechnical Properties of Mine Tailings Journal of

Characterization of the Tailings. The basic geotechnical properties of the four tailings are summarized in Table 1, and Fig. 1 displays the grain size distributions. The specific gravity of the coarse and fine iron tailings are 3.23 and 3.08, respectively, which are consistent with those of metal tailings but much higher than those of natural soils.

Mine Tailings an overview ScienceDirect Topics

Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content. Tailings are transported from the mill and are discharged into an impoundment as a slurry containing ∼30 wt.% solids.

Jul 19, 2019 Driven by mining volumes, globally generated tailings are estimated to total up to 3.2 billion tons for copper and up to 1.8 billion tons for iron per year. Water conservation and the cost of

Tailings Rio Tinto

As the tailings slurry is collected in the impoundment, the water separates from the heavier sand and silt particles and is collected at the surface. The tailings pond water is then recycled back into the operation for reuse and the tailings may be reclaimed so as to minimise the impact on the environment.

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), which are rejected from the sought-after ores of copper and nickel, as well as coal. Although harmless underground, these minerals are

The unwanted material, or tailings, is returned to the mined areas to help return it to its original form. Tailings deposit areas are contoured to recreate the original land forms. Marram grass and radiata pine trees are planted to stabilise deposits and minimise wind-blown sand. The tailings consist of river water containing clays and sands.
