“…6). The decrease in the bio-available fraction of the heavy metals is mainly due to a direct effect of the pH, which favours the processes of adsorption, precipitation and co-precipitation with oxihydroxides; the formation of chelates; the formation of metallic carbonates and, the formation of metallic phosphates (Alvarenga et al, 2008;Liu et al, 2009;Fernández-Caliani and Barba-Brioso, 2010;Zornoza et al, 2013). This is promising in areas with quarries which produce carbonate material (limestone, dolomite, marble) and where there is extra production of organic residues such as pig slurries, since these residues can be used as amendments to reclaim bare main soils with low or no cost (depending on transportation and application), turning them into valuable by-products.…”

“…El descenso en la concentración de la fracción biodisponible de los metales pesados se debe fundamentalmente a un efecto directo del incremento del pH, que favorece los procesos de adsorción, precipitación y coprecipitación con oxihidróxidos, a la formación de quelatos con la materia orgánica, a la formación de carbonatos metálicos (aportados por el lodo de mármol) y a la formación de fosfatos metáli-cos (aportados por el purín de cerdo) como consecuencia de la aplicación de las enmiendas (Alvarenga et al, 2008;Liu et al, 2009;Fernández-Caliani y Barba-Brioso, 2010;Zornoza et al, 2013). observaron que la formación de complejos orgánicos y la precipitación como fosfato eran procesos muy efectivos la para la inmovilización del Cd, mientras que la adición de carbonatos era necesaria para reducir la biodisponibilidad del Pb y del Zn.…”

Zornoza, R. et al., 2017. Rehabilitación de una presa de residuos mineros mediante la aplicación de lodo de mármol y purín de cerdo para el desarrollo de una fitoestabilización asistida. Boletín Geológico y Minero, 128 (2) RESUMENLas acumulaciones de residuos mineros abandonados presentan riesgos ambientales y de salud pública por la potencial transferencia de metales pesados tóxicos a través de la erosión hídrica y eólica o lixiviación. Para reducir estos riesgos, se ha desarrollado una estrategia de rehabilitación en una presa de residuos mineros basada en la fitoestabilización asistida. A lo largo de 2011 se aplicó sobre la superficie de la presa lodo de már-mol (6.7 kg m -2 ), purín de cerdo (1.7 ,7 L m -2 en julio y 2.6 L m -2 en septiembre), y la fase sólida de purín de cerdo (7 kg m -2 ). En primavera de 2012 se introdujeron trece especies vegetales autóctonas. Durante dos años (2012-2013) se ha monitorizado con carácter semestral la evolución de diferentes propiedades edáficas y la fracción biodisponible de los metales Cd, Pb y Zn. Los resultados mostraron un incremento en el pH (de ~3 a ~7), la estabilidad de agregados (de 7% a 10-15%), el carbono orgánico (de 3.5 g kg -1 a 3.5 g kg -1), el nitrógeno total (de ~0.3 g kg -1 a ~0.8 g kg -1) y la capacidad de intercambio catiónico (de 6 cmol+ kg -1 a 11 cmol+ kg -1 ) con la aplicación de las enmiendas y el desarrollo de la vegetación, mientras que la fracción biodisponible de los metales descendió drásticamente (90-99%). Por tanto, la estrategia seguida ha resultado positiva para reducir la biodisponibilidad de metales pesados, mejorando la calidad y fertilidad del suelo. Estos resultados son prometedores en áreas donde se generen residuos que puedan ser utilizados para la rehabilitación de suelos afectados por metales pesados, revalorizando los mismos y al convertirse en subproductos de utilidad.Palabras clave: Presa de residuos, enmiendas, geoquímica, metales pesados, minería.

“…The behaviour of Mn was not as clear during the first week of the experiment as in the case of previous elements (the concentrations changed rapidly from the beginning till the day 14), but in the end, again, no significant differences were recorded between the control and organic treatments (Figure 1c). The concentrations of Cu, similarly to Zornoza et al (2013), were not affected by fertilizer treatment at all (Figure 1b).…”

The 28-day incubation experiment was carried out to evaluate the impact of the application of digestate (Dig); digestate with straw (DigSt); pig slurry (Slu) and mineral fertilizer (NPK) on Cd, Cu, Mn and Zn availability, on K 2 SO 4 -extractable carbon content and on the soil pH value in long-term contaminated soil. At days three and seven of the experiment, the 0.01 mol/L CaCl 2 -extractable fractions of Cd, Zn and Mn significantly decreased under organic treatments (Dig, DigSt and Slu) with the most pronounced effect under Dig treatment. The NPK treatment caused the increase of risky element concentrations since day 21 of incubation which was accompanied with pH decrease. The contents of 0.5 mol/L K 2 SO 4 -extractable carbon were the highest at day 3 and 7 of incubation in organic treatments. The significant correlations between 0.5 mol/L K 2 SO 4 -extractable carbon and CaCl 2 -extractable metal concentrations showed a close relationship between fresh organic matter added in organic fertilizers and risky element availability, suggesting that newly added labile organic matter can form temporary ligands with risky elements and release them later following its decomposition.

“…Tailings pond and stope may produce serious safety threat and environmental pollution (Coulibaly et al, 2017;Stovern et al, 2015). Accurate and timely monitoring of stopes and tailings ponds is of great significance to guide the regional environmental governance, disaster prevention, and ecological restoration (Hu et al, 2017;Mohamed et al, 2008;Zornoza et al, 2013). However, less research has been done for extracting the above information by use of remote sensing images.…”

ABSTRACT:With the development of economy, global demand for steel has accelerated since 2000, and thus mining activities of iron ore have become intensive accordingly. An ultra-low-grade iron has been extracted by open-pit mining and processed massively since 2001 in Kuancheng County, Hebei Province. There are large-scale stopes and tailings ponds in this area. It is important to extract their spatial distribution information for environmental protection and disaster prevention. A remote sensing method of extracting stopes and tailings ponds is studied based on spectral characteristics by use of Landsat 8 OLI imagery and ground spectral data. The overall accuracy of extraction is 95.06%. In addition, tailings ponds are distinguished from stopes based on thermal characteristics by use of temperature image. The results could provide decision support for environmental protection, disaster prevention, and ecological restoration in the ultra-low-grade iron ore mining area.
