Iron Mine Tailing Characterization

Geophysical characterization and monitoring for mine tailings can help reduce environmental impacts, improve safety, and ensure long-term stability of these structures. Heap Solutions offers unique tools and services specific to mine tailings needs.

Waste Mine Tailings Characterisation As described above, copper and uranium mining, iron mining, and phosphate mining occur predominantly in the Southwest, Minnesota, and Florida, respectively. Therefore, it is not surprising that approximately 75 percent of all mining wastes generated in the metal-ore and non-metal mineral mining

01-12-2018· Mine tailings and wastes may contain metals, such as iron, copper, nickel and zinc, in relatively high concentrations (from 0.5 to 3%), and occasionally precious metals such as gold and silver. Toxic elements, such as arsenic, may also be present in concentrations up to 100 mg/kg ( …

Preliminary study of the core has involved characterisation of a section at 44 m depth, and a section at 77 m depth. ˜ e shallower sample has brown tailings, indica-tive of iron oxide minerals produced during pressure oxidation. ˜ e deep sample is grey, similar to the original colour of the schist. ˜ e tailings porewater at both depths

4.2.1 Mine tailings. Total ferric iron (Fe 2 O 3total), S, and trace element (Ag, As, Au, Cd, Cu, Ni, Pb, Sb, Sn, and Zn) concentrations, and pH values from tailing samples of the four mine district are summarized in Table 3. All samples showed a pH range of 2.2–5.6. This value range reflects the typical acid character of stored mine tailings.

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.

geochemical techniques are needed for tailings characterization during and after mining ceases , especially at iron ore mines, yet an up -to-date set of methods is not available in best practice guidance documents. As we learn more from past failures, best practice characterization

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 ...

To aid the structural characterization, synthetic iron(III)-arsenate co-precipitates were prepared to mimic the actual uranium mill tailings neutralization products. The principle components analysis method was used to validate the synthetic amorphous scorodite as a primary model compound for arsenate species in the raffinate samples under the specific precipitation conditions.

Metal sulfide mine wastes (tailings), generated during 125 years of mining and smelting activities, contaminate 200 km of riverine habitat in the Upper Clark Fork Valley of Western Montana (8, 26, 32, 36).Fluvial redeposition of these wastes along the floodplain has created vast wastelands, called slickens, void of vegetative cover.

Bacterial diversity in mine tailing microbial communities has not been thoroughly investigated despite the correlations that have been observed between the relative microbial diversity and the success of revegetation efforts at tailing sites. This study employed phylogenetic analyses of 16S rRNA genes to compare the bacterial communities present in highly disturbed, extremely (pH 2.7) and ...

During the dry season, iron-sulfate salts precipitate by capillary transport on the tailings and at the foot of DC2 (tailings impoundment DC2) tailings dam where an acid, Fe 2+ rich plume outcrops. The most abundant compounds in the acid mine drainage (AMD) are SO 4 2− , Fe 2+ , Fe 3+ , Zn 2+ , Al 3+ , Mg 2+ , Cu 2+ , As 3+/5+ , Cd 2+ .

presence of iron minerals is believed to be particularly important to arsenic mobility. Extraction methods were used to evaluate arsenic and iron in a variety of contaminated materials including mine tailings and soils. The contaminated materials were also evaluated for …
