Abstract

Gunumuzde ticari alumina uretiminin neredeyse tamami hammadde kaynagi olarak boksit cevherlerinin kullanildigi Bayer prosesiyle karsilanmaya devam etmektedir. Bayer prosesine dogrudan beslenebilir metalurjik kalitedeki boksitler icin en onemli kriterlerden birisi cevherin toplam silis miktarinin bilinmesidir. Cunku, boksit lici sirasinda cozunme egilimi gosteren reaktif silis asiri miktarda kostik soda tuketimine yol acmakta ve ciddi oranda alumina kayiplarina neden olmaktadir. Bundan dolayi boksitin reaktif silis icerigi, Bayer prosesinin etkin ve ekonomik uygulanabilirligi uzerinde belirleyici bir rol oynamaktadir. Silis turlerinin boksitten uzaklastirilmasi islemi (on desilikasyon) bircok alumina uretim tesisinin uzerinde calistigi ana konulardan birisidir. Son yillarda kopuk flotasyonu gibi bazi zenginlestirme yontemlerinin on desilikasyon amaciyla denendigi bilinmektedir. Bu calismada, boksit cevherindeki reaktif silisin sebep oldugu baslica sorunlar ve on desilikasyon amaciyla uygulanan birtakim zenginlestirme yontemleri guncel kaynaklardan derlenerek ozetlenmistir. Bu yontemler arasinda gerek silis uzaklastirma verimi gerekse tesis olceginde uygulanabilme bakimindan ozellikle flotasyonun daha fazla onem kazandigi belirlenmis ve bu konuda genis kapsamda bir degerlendirme yapilmistir.

不要对十进制前拳击行业的工作感到可笑。
如今,商业化的氨基甲酸铝继续与拜耳工艺混合,拜耳工艺被拳击珠宝用作几乎所有产品的来源。拜耳工艺中实际可以进料的金属盒的十个标准之一是了解珠宝的硅总量。因为氧化物中的活性硅酸是由循环系统中大量的tuketimin钠和大量的kayipolina铝引起的。因此,盒子的活性硅冰柜对拜耳工艺的有效性和经济性起着决定性作用。钙尿道的主要课题之一是从盒子里取出几个铝尿道。近年来,一些最富有的元素,如地震舰队,已被确定为十分位的目标。在这场灾难中,拳击首饰中的活性硅引发了压力问题,最近的消息来源抑制了未来十年用于小数目的的疲软。如果确定这些化合物之间所需的硅去除数据表明,在工厂的能力范围内,已经获得了超过一盎司的浮选,则其在很大范围内已经减少。

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.
