Abstract
Bu calismada, Puturge (Malatya) pirofillit yatagindan alinan %23,6 Al2O3 icerikli cevherden asit lic islemiyle aluminyum (Al) kazanimi uzerine aktivasyon kosullarinin etkisi arastirilmistir. Bu kapsamda, baslangicta aktive edilmemis tuvenan cevher ile daha sonra kalsinasyon ve asiri ogutme yoluyla aktive edilmis cevherler HCI ile lic edilmistir. Elde edilen deneysel calisma bulgularina gore; tuvenan, kalsine ve asiri ogutulmus cevher icin lic cozeltisinde Al kazanimi sirasiyla %10,57, %33,63 ve %86,5 olarak bulunmustur. Kalsinasyon islemi sirasinda kil tabakalari arasinda yeterli bir acilmanin olmadigi ve gozenekli yapinin elde edilemedigi, ayrica yuksek sicakliklarda asitte cozunmeye direncli yeni mineral fazlarinin ortaya ciktigi tespit edilmistir. Bu nedenle termal yolla aktiflestirilmis cevher icin Al kazanimi nispeten dusuk cikmistir. Ote yandan asiri ogutmeyle saglanan mekanik aktivasyonun cevherdeki kil minerallerinin amorflasmasina yol actigi, boylece aluminyumun cozeltiye gecme egiliminde onemli bir iyilesme sagladigi gorulmustur. Sonucta termal aktivasyonun kismen, mekanik aktivasyonun ise cok belirgin bir sekilde Al kazanimini artirdigi sonucuna varilmistir.
期刊介绍:
Scientific Mining Journal, which is published i n open access electronic environment and i n printed, is a periodical scientific journal of Union of Chambers of Turkish Engineers and Architects Chamber of Mining Engineers. The name of the journal was "Mining" until June 2016 and it has been changed to "Scientific Mining Journal" since September 2016 because it can be confused with popular journals with similar names and the ISSN number has been updated from 0024-9416 to 2564-7024. Scientific Mining Journal, published four times a year (March-June-September-December), aims to disseminate original scientific studies which are conducted according to the scientific norms and publication ethics at national and international scale, to scientists, mining engineers, the public; and thus to share scientific knowledge with society. The journal is in both Turkish and English. The journal covers theoretical, experimental, and applied research articles, which reflects the findings and results of an original research i n the field of mining engineering; review articles, which assess, evaluates, and interprets the findings of a comprehensive review of sufficient number of scientific articles and summarize them at present information and technology level; technical notes, which may be defined as a short article that describes a novel methodology o r technique; a case studies, which are based on the theoretical o r real professional practice and involves systematic data collection and analysis.
