The aim of our work was to characterise the stability, humification degree, and principal classes of fluorophores in humic acids isolated from different matrices. Soil humic acids were isolated from a...
The aim of the study is the characterisation of the optical properties of mining lakes. These optical properties will be used to the classification of remote sensing data and the spatial and temporal ...
Fuel shortages and resultant rising fuel costs as well as federal policies prompting energy independence have served to encourage power companies to exploit available lignite deposits of the western s...
Among the various possibilities of limiting the disposal of fly ashes (lignite), their reutilization as adsorbent materials is worthy of consideration. To this end, proper ashes beneficiation techniqu...
The Neyveli Lignite Corporation (NLC) is among the largest lignite based power plants in South East Asia. The four elevated stacks from this power plant emanate a substantial amount of sulphur dioxide...
Results of experimental studies determining the increase of the humic acids soluble in alkaline medium and represented by the carboxyl groups (COOH) during the oxidation of an Elbistan lignite sample ...
Calcalkaline volcanism and volcaniclastic deposition controlled considerable mode of late Miocene sedimentation and basinal development of the lignite-bearing Soma basin in western Turkey. The volcani...
Data indicate that surface mining is safer than underground mining. The preponderant injury categories are, aspirin, contusion, cut, and fracture; the preponderant illness category is 'dust diseases o...
The adsorption of Triton X-100 in aqueous solution on the less than 53 \mm size fractions of Tunçbilek lignite and Zonguldak bituminous coal was studied. The adsorption isotherms were formed fo...
The mineralogy of partially kaolinized strata interbedded with lignite at the San Miguel mine, Atascosa County, Texas, was investigated by X-ray powder diffraction and optical and scanning electron mi...
Abstract: Mineralogical weathering sequences in sediments overlying lignite beds were investigated in a core (27 m deep) from Calvert, Robertson County, northeast Texas. Weathering trends were evaluat...
This study was conducted for the Office of Water Resources Research and Technology in the U.S. Department of the Interior by the Texas Engineering Experiment Station at Texas A&M University. The proje...
