Understanding Selenium Mobility by Sorption and Extraction Processes in Surface Coal Mine Spoil
Surface coal mine spoil was studied to evaluate selenium (Se) mobility and solubility using batch experiments, column-Ieachmg techniques, and sequential and individual extraction processes. Both selenite and selenate followed linear isotherm patterns at relatively lower Se treatments, whereas over a broader solution Se concentraton range the sorption mechanism followed the Lanpuir model. The va...
متن کاملSelenium Adsorption onto Iron Oxide Layers beneath Coal-Mine Overburden Spoil.
A field experimental study to determine the feasibility of sequestering dissolved selenium (Se) leached from coal-mine waste rock used an iron (Fe)-oxide amendment obtained from a mine-drainage treatment wetland. Thirty lysimeters (4.9 × 7.3 m), each containing 57.7 t (1.2-1.8 m thickness) of mine-run carbonaceous shale overburden, were installed at the Hobet mine in southeastern West Virginia....
متن کاملGeotechnical Properties of Mine Fill
Mine fill is the material placed underground to fill the voids created by mining excavations. It provides overall large scale ground stabilization while allowing localized pillar recovery. In addition to providing a working floor or back, mine fill has the potential to reduce subsidence and minimize dilution. Mine fill is essential to cut and fill, benching and sublevel stoping mining methods. ...
متن کاملCoal-mine hollow fill and settling pond influences on headwater streams in southern West Virginia, USA.
The influences of coal-mine hollow fills and associated settling ponds in three headwater streams were assessed in southern West Virginia, USA. Fill drainage waters had elevated conductivities and metal concentrations, compared to a regional reference. Benthic macroinvertebrate richness was not affected consistently by the hollow fill drainages, relative to a regional reference, although a more...
متن کاملAssessment and Distribution of Heavy Metals in Mung Bean Vigna Radiata Cv. Local) Grown on Coal Mine Spoil
Availability and uptake of heavy metals (Zn, Cu, Fe, Al, Cr, Ni) by mung bean grown on coal mine spoil was studied. The experiment was carried out as a pot culture experiment using garden soil and different proportion of coal mine spoil. The heavy metals were transported to roots then shoot and were found in traces in the fruits. No toxicity symptom was reported during vegetative as well as rep...
