Soil quality changes in an Iberian pyrite mine site 15
Heavy metal pollution arising from mining and smelting activities is a major environmental issue (Beane et al. 2016), unless proper reclamation measures are implemented to reduce acidity, decrease metal mobility and improve soil quality. This is particularly true in regions with a long history of mining and mineral processing like the Iberian Pyrite Belt (IPB) of Spain and Portugal, where many of the old mines

Results showed that soil quality changed noticeably over the study period (2003-2018), with overall improvements in key properties, such as structural stability, cation exchange capacity, degree
The Brukunga Pyrite Mine –South Australia A Review of
2006-5-29 The Nairne Pyrite Mine at Brukunga, opened as a source of sulphur for the production of H 2SO 4 to be used in the production of superphosphate fertiliser in 1955 and operated as an open pit until cessation of production in 1972. For two years after closure, two caretakers remained on site until the mining lease expired in 1974. The South
Effects of mining activities on evolution of water quality
The resulting δ 34 S SO4 values suggest that the dissolved sulfate source in the surface water is mainly pyrite oxidation but atmospheric precipitation for the karst groundwater. Given the similar chemistry and isotopic composition between surface water and partial groundwater, it is reasonable to assume that most of the dissolved sulfate source in part of the groundwater was derived through the oxidation of pyrite
Hydrogeological and environmental impact of Amjhore pyrite
Oxidation of pyrite in mining waste or overburden is the main source of acid mine drainage (AMD) production which causes major environmental pollution. Presently, the most common method of controlling AMD problems is through the mixing alkaline substances, such as limestone, with the AMD producing materials.
Pyrite: The mineral pyrite information and pictures
Pyrite was once used as a source of sulfur, but is now only a minor ore for both sulfur and iron. Pyrite from some localities is auriferous, and therefore is used as an ore of gold in gold-bearing localities.Pyrite was polished by the Native Americans in the early times and used as mirrors. Today, it is used as an ornamental stone, as well as a very popular stone for amateur collectors.
Valorization of iron pyrite from coal mining in southern
2019-2-1 The raw R1 pyrite waste sampled from mining companies in southern Santa Catarina state (Brazil) presented the yellowish coloration that is characteristic of pyrite, which was amid the dark tones that are characteristic of the coal mineral. Whitish features of other rocky materials were also present in the raw material, as shown in Fig. 2.
Pyrite: Mineral information, data and localities.
Pyrite is quite easy to distinguish from gold: pyrite is much lighter, but harder than gold and cannot be scratched with a fingernail or pocket knife. Pyrite is commonly found to contain minor nickel, and forms a series with Vaesite; Bravoite is a nickeloan variety of pyrite. It usually contains minor cobalt too and forms a series with Cattierite.
Element mobility during pyrite weathering: implications
2005-10-5 The mining waste consists of pyrite (∼10 wt%), other sulfide minerals (less than 0.5 wt%), and nonsulfide minerals (∼ 90 wt%). The most abundant nonsulfide minerals are quartz, feldspar, pyroxene, clay minerals and about 5–7 wt% calcite.
Water quality assessment in the Bétaré-Oya gold mining
2018-1-1 The influence of gold mining activities on the water quality in the Mari catchment in Bétaré-Oya (East Cameroon) was assessed in this study. Sampling was performed within the period of one hydrological year (2015 to 2016), with 22 sampling sites consisting of
