بررسی عناصر کمیاب و خاکی نادر در حوزههای زغالی ایران (در معدن زیر زمینی زغالسنگ کارمزد)
This research presents data on widespread abnormal accumulations of Trace and Rare Earth Elements in many coal deposits worldwide. There have been many studies on the distribution and geochemistry of REEs in coal. ∑REE content in most coals varies from several µg/g to several hundred µg/g, and the REEs are distributed in minerals although some are associated with organic material in coal. In th...
متن کاملGeological Controls on Mineralogy and Geochemistry of an Early Permian Coal from the Songshao Mine, Yunnan Province, Southwestern China
This paper discusses the content, distribution, modes of occurrence, and enrichment mechanism of mineral matter and trace elements of an Early Permian coal from Songshao (Yunnan Province, China) by means of coal-petrological, mineralogical, and geochemical techniques. The results show that the Songshao coal is characterized by high total and organic sulfur contents (3.61% and 3.87%, respectivel...
متن کاملGeochemistry of Major, Trace, and Rare Earth Elements in Biglar Permo-Triassic Bauxite Deposit, Northwest of Abgarm, Ghazvin Province, Iran
Biglar Permo-Triassic bauxite deposit is located in ~15 km northwest of Abgarm, southwest of Ghazvin province, west of central Iran. It consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of Ruteh (Permian) and Elika (Triassic) carbonate formations. Petrographically, the bauxite ores exhibit collomorphic-fluidal, pseudo-breccia, pseudo-porphyritic, panidio-morphic-...
متن کاملGeochemical and Mineralogic Characterization of Solids and Their Effects on Waters in Metal-mining Environments
The geologic characteristics (ore mineralogy, geochemistry, host rock lithology, etc.) that economic geologists use to classify mineral deposits are key to understanding their environmental signatures. Mineralogic characterization and chemical analysis are among the many scientific tools that can be applied to mining-environmental prediction, mitigation, and remediation (Plumlee and Logsdon, 19...
متن کاملسنگشناسی، ژئوشیمی و جایگاه زمینساختی مجموعهی گرانیتوئیدی رودره (جنوب بیرجند)
The oxidation of sulfide minerals in coal and mine's waste materials produce acid mine drainage. The evaporation, oxidation, dilution and neutralization of this acid drainage lead to formation of secondary minerals. Due to having broad surface spreading these minerals have the potential of maintaining sulfates and many of the metallic elements. In order to carry out mineralogical and geochemica...
