In general, fixed carbon and gross calorific values of the Edire and Balkaynak coals are higher than Güvercinlik and Çerçi coals. The highest ash yields were observed in the Çerçi coals. The concentrations of Mg, P, Ca, Mo, Y, Ni, U, Zn, Ga, Ba, W, Sr, Ta, and Be of the analysed coals are positively correlated with ash yield, indicating an organic affinity. The Lias-aged coals located in Gümüşhane and Bayburt are low-rank coals.</dc:description><dc:publisher>Taylor and Francis Inc.</dc:publisher><dc:date>2016</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/gumushane/13350</dc:identifier><dc:identifier>https://doi.org/10.1080/15567036.2013.820235</dc:identifier><dc:identifier>1556-7036</dc:identifier><dc:language>en</dc:language><dc:relation>Energy Sources, Part A: Recovery, Utilization and Environmental Effects</dc:relation><dc:rights>info:eu-repo/semantics/closedAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/13350</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
