zeolite was synthesized from coal tailings and coal fly ash sampled from zarand coal washing plant, iran, using h2o2–promoted hydrothermal treatment. samples consisted mainly of sio2 and al2o3 which are the main components for the zeolite synthesis. to perform the experiments, appropriate amount of the starting materials were mixed with 240 ml volume of 30% h2o2 at room temperature with continu...

The role of Fe oxyhydroxides dynamic on metal bioavailability was studied in the Rio Doce estuary after largest mining disaster world. Soon 2015, metals were associated with under a redox-active estuarine environment. Our results indicate that organic matter inputs from plant colonization deposited tailings over soils led to reductive dissolution within two years. Soil pseudo-total content decr...

In similar experiments conducted in 1996 and 2009, yellow perch (Perca flavescens) were stocked into two experimental systems: a demonstration lake where oil sands fine tailings were capped with natural water and a lake in a watershed containing bitumen-bearing sodic clays. In both experiments, yellow perch were captured in May from a nearby reservoir and released into the experimental ponds. P...

The foundation of the natural world is soil, which prevalent in many parts India and has a high silt content, low strength, weak bearing ability. loads placed on these soils during construction or structures useful life are too great for them to bear. In India, expansive soil covers 20 percent land. To enhance functionality soils, stabilization used.In this research work, an attempt been made u...

We assessed the contents of Fe, Ni, Cu, Zn, As, Cr, Pb, Hg in soils residential settlements and surrounding areas exposed to anthropogenic load due mining activities. The study object is located Kuznetsk Alatau (part Sarala gold ore cluster – SGOC), village Priiskovy its tailings dump, Ordzhonikidzevsky, Republic Khakassia). background SGOC are following: Fe 3.08–5.06 %, Ni 24.74–45.13 g/t, Cu ...

Medicinal plant consumption can be a source of human exposure to radioactive elements such as (238)U and (232)Th, which can lead to internal radiation doses. The uptake of (238)U and (232)Th from soils to the leaf samples of three different medicinal plant species (Eucalyptus globulus, Acacia mearnsii and Hyparrhenia filipendula) from the purlieu of the Princess gold mine dump, an abandoned con...

This study was carried out to 1. determine spatial variations of heavy metal deposition in agricultural soils of two rural communities (OuledBouAicha and Tazakourte) of about 5790 ha in a mining area near Marrakech city in Morocco; 2. to assess the extent of metallic pollution generated by the mining activity and; 3. to identify the key mechanism responsible for this contamination and its relat...

The recovery of degraded areas is imperative for the sustainability mining activities. main action implemented to improve chemical, physical and biological conditions soils, tailings sterile deposits incorporation organic material. Biosolids (hygienized sewage sludge) are among materials that can be applied. However, considering health risk they represent, not all suitable receiving this waste....
