This study assessed the geochemical impact of mine tailings reclamation on the quality of soils from the AngloGold Concession, Obuasi, Ghana. Soil samples from mine tailings reclamation sites were evaluated for the concentrations of plant nutrients and trace metals. Contaminations of trace metals, using geochemical pollution indices were used to assess possible effects on agriculture and liveli...

There is a continual influx of heavy metal contaminants and pollutants into the biosphere from both natural and anthropogenic sources. A complex variety of abiotic and biotic processes affects their speciation and distribution, including adsorption onto and desorption from mineral surfaces, incorporation in precipitates or coprecipitates, release through the dissolution of minerals, and interac...

We determined the urinary 1-hydroxypyrene (1-HP) concentration and the creatinine-adjusted 1-HP concentration in 644 randomly selected Dutch children, aged 1-6 years and living in five areas with roughly different levels of polycyclic aromatic hydrocarbons (PAHs) in soil and ambient air. The presence of other factors that might influence the exposure to PAHs was studied using a questionnaire. T...

Large areas of land are needed to dispose of wastes produced by mining activities worldwide which poses a myriad of environmental hazards with regards to soil, water and air contamination. This is a problem, especially for a mining country like South Africa, where more than 1500 mines are registered which affects 0.2 million ha of land. Legislation in this country do, however, stipulate that di...

Mavres Petres mine is an underground mine, located in Chalkidiki, northern Greece, that owned and operated by Hellas Gold; a wholly subsidiary of Eldorado Gold Corporation. The extracts highgrade lead zinc orebody using drift fill mining method. Backfill integral part cycle at mine. Filtered coarse tailings mixed with cement are used for making cemented hydraulic backfill surface batching plant...

Oil sands surface mining in Alberta has generated over a billion cubic metres of waste, known as tailings, consisting sands, silts, clays, and process-affected water that contains toxic organic compounds chemical constituents. All these tailings will eventually be reclaimed integrated into one two types mine closure landforms: end pit lakes (EPLs) or terrestrial landforms with wetland feature. ...
