Abstract

Yuksek teknoloji uygulamalarindaki guncel gelismeler, yuksek saflikta kuvars gibi silikatlara olan artan talebi gozler onune sermistir. Bu nedenle, bu calismanin konusu pirometalurjik ve devaminda hidrometalurjik uygulamalarla kuvars cevherinin saflastirilmasi olarak belirlenmistir. Bu calismada, konsantre Fe tenoru ile renk degerleri arasindaki iliskiyi daha iyi anlamak icin kuvarsin termal islem ve ardindan oksalik asit (OA) ile agartilmasi arastirilmistir. Termal islem sicakliginin kuvarsin OA ile agartilmasi uzerinde onemli bir etkiye sahip oldugu bulunmustur. Hem termal islem gormemis hem de 250°C'ye kadar sicakliklarda termal islem gormus kuvarstan en yuksek oranda Fe uzaklastirildigi gozlenmistir. 400°C - 900°C arasi sicakliklarda gerceklestirilen termal islem sonucu en basarisiz saflastirma performanslari gozlenmistir: L* degeri dusmus, a* ve b* degerleri artmistir. Termal islem sicakliginin 1100°C’ye artirilmasi sonucu agartma basarisiz olmus: en dusuk oranda Fe uzaklastirilirken, buna karsin en yuksek L* degeri ve en dusuk a* ve b* degerlerini saglayan en basarili renk degerlerine ulasilmistir. Bu bulgu cozunmeye direncli demir silikatlarin olusumu ile aciklanmistir. Ayrica kuvars cevherinden okzalik asit lici ile demir uzaklastirma orani ve renk degerlerinde gozlenen farkliliklar; termal islem sonucu kristalin yapidaki degisiklikler ve mikro catlaklarin olusumu ile aciklanmistir.

火法冶金和湿法冶金工艺对石英矿净化的联合作用

高科技应用的最新发展包括对硅酮的需求增加，如高患病率的厨师。因此，calismus的物质被定义为高温铝和连续的湿法冶金应用于烹饪珠宝的飞溅。在加利福尼亚州，这是一个很好的例子。终端查询合同对OA产生了不错的影响。即使你不想要热量，从热锅炉到250°C，Fe的速率也是最高的。在400°C和900°C之间产生的热伊斯兰导致最低的波动性能：L*退化、a*和b*退化。在1100°C的温度下，由此产生的热岛病伪影可以降低到Fe温度下的最低色度，即最高的L*度和最低的a*和b*度。抗反射硅酸铁的组成加速了这一发现。此外，铁与烹饪天花板的距离水平和辛醇的颜色降解差异；热伊斯兰的结果是，没有退化和显微镜，晶体不会加速。

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.
