Conventional deposits of rare earth elements (REEs) cannot meet the high demand for REEs globally. Therefore, prospecting from alternative sources like ash coal is vital. In this study, discard and “Run Mine” (ROM) were studied to evaluate abundance association in these materials. The TESCAN Integrated Mineral Analyzer (TIMA) X-ray diffractometer (XRD) techniques employed determine mineralogy s...

Haerwusu Surface Mine of the Jungar Coalfield is a large coal mine. Its formation environments have not been reported in detail. In order to reconstruct paleoenvironment peat formation, nine samples were collected, and analyzed using microscope, column chromatography, gas chromatography (GC), chromatography–mass spectrometry (GC–MS). According results microscopic analysis, average random vitrin...

The correlation between local mechanical (elasto-plastic) and structural (composition) properties of coal presents significant fundamental and practical interest for coal processing and for the development of rheological models of coal to coke transformations. Here, we explore the relationship between the local structural, chemical composition, and mechanical properties of coal using a combinat...

The Hushpuckney Shale Member of the Swope Formation (Missourian Stage, eastern Kansas) is the core shale of a Kansastype cyclothem, formed during the late transgressive to early regressive phases of a Late Pennsylvanian glacio-eustatic cycle. Coeval high-frequency climato-environmental dynamics of the Midcontinent Seaway are preserved in the KGS Orville Edmonds No. 1A study core as centimeter-s...

The petrology of coal, as determined by the microscopic analysis organic and inorganic elemental constituents provides information on its nature characteristics. Coal is used worldwide in production thermal energy coke. In case high-quality Colombian coals, only limited studies have been carried out. present study presents geochemical, mineralogical, petrological characteristics coal samples co...

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...

The purpose of this study is to characterize the relationship between organic material and thermal maturity during the process of evaluation of hydrocarbon potential. Samples studied include Miocene high volatile bituminous coal and coaly shale collected from outcrops and exploration wells in Hsinchu-Miaoli area, NW Taiwan, density centrifuge separated macerals, bituminous coal and anthracite f...
