Abstract

Bu calismada, Demir Export A.Ş.’ye ait demir cevheri numunesinin konvansiyonel manyetik ayirma ile zenginlestirmesine yonelik stratejiler degerlendirilmistir. Calismada kullanilan demir cevheri %53,20-53,78 Fe icerigine sahip olup, SiO2 icerigi %10,5’in uzerinde olculmustur. Al2O3 icerigi ise %2,3’un, toplam alkali icerigi (K2O+Na2O) ise %0,6’nin uzerindedir. Bu ozellikleri ile cevherin satislara temel teskil eden analiz degerleri, Fe icerigini sorunsuz olarak saglamaktadir. Fakat silis, alumina ve alkali icerikleri red siniri olarak tanimlanan degere cok yakin ya da bir miktar uzerinde olmaktadir. Deneysel calismalar ozellikle impurite iceriginin cikardigi bu sorunlari gidermeye yonelik olarak gerceklestirilmistir. Mevcut uretim yontemi goz onune alinarak gelistirilen yontemin kuru bir ayirma yontemi olmasi gerekliligi belirlenmis ve bu nedenle kuru manyetik ayirma testleri planlanmis ve yurutulmustur. Ayrica cevherden uretilebilecek en kaliteli urun ozelliklerini ortaya koyabilmek amaciyla agir sivi testleri de uygulanmistir. Deneysel calismalar sonucunda -30+10 mm ve -10 mm fraksiyonlarinda sirasiyla agirlikca %68 (%61,26 Fe) ve %92 (%55,39 Fe) oraninda urunler alinabilecegi belirlenmistir.

在这场灾难中，iron Export A.S.的铁样品被剥夺了削弱传统磁场分布的所有策略。calima中使用的铁天花板由53,20-53,78Fe冰原组成，导致calima的10.5%中含有SiO2冰原。Al2O3冰淇淋为2.3%，总碱冰淇淋（K2O+Na2O）为0.6%。对这些榛子和珠宝卫星的分析表明，铁冰原与此无关。但硅树脂、铝和酒精物质通常被定义为红色神经，它们非常接近或非常小。为了解决这些大气中固有的问题，经常会遇到实验性的卡路里。现有的尿道氮已被确定为一种干骨发射化合物，这就是为什么要计划并全面进行干磁发射测试的原因。此外，为了证明可以从珠宝中获得的最高质量的干旱危害，还应用了敏捷灰色测试。实验校准的结果表明，在-30+10 mm和-10 mm的分数下，大约68%（61.26 Fe）和92%（55.39 Fe）的子弹可以被杀死。

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.
