Abstract

Fosfat cevheri, kritik oneme sahip hammaddelerin ekonomik onemini ve tedarik riskini vurgulayan Avrupa Komisyonu raporuna gore, tum canlilar (bitkiler, hayvanlar ve insanlar) icin en kritik hammaddelerden biridir. Bu sebeple; dusuk tenorlu fosfat cevherinin degerlendirilmesi onem arz etmektedir. Bu calismada, fosfat cevherinin icerdigi karbonatli minerallerin (kalsit ve aragonit) selektif olarak uzaklastirilmasi kalsinasyon-sakkaroz lici yontemleri uygulanarak arastirilmistir. Calismada kullanilan cevherin karakterizasyonu X-isini difraksiyon (XRD), termogravimetrik (TG) ve X-isini fluoresans (XRF) spektroskopisi ile belirlenmistir. Kalsinasyon sicakligi (750, 850 ve 900 ˚C) ve suresinin etkisi (15, 30, 60, 90 ve 120 dk) incelenmistir. Sakkaroz ile yapilan lic islemlerinde ise karistirma hizi (0, 150, 300, 450 dev/dk, sakkaroz konsantrasyonu (0, 0,25, 0,50, 1, 1,50 ve 2 M) ve lic suresinin (15, 30, 60, 120, 180 ve 240 dk) etkileri ortaya konmustur. Sonuc olarak; kuvars iceriginin yuksek olmasi, kalsinasyon islemi sirasinda istenmeyen CaSiO3 minerali olusmus olsa da karbonatli minerallerin selektif olarak cevherden uzaklastirilmasi saglanmistir.

FOSFAT仍然与碳酸盐化的mynister没有区别

Fosfat cevheri，kritik oneme sahip hammadelerin ekonomik onemini ve tedarik riskini vurgulayan Avrupa Komisyonu raporuna gore，tum canlilar（bitkiler，haywalar ve insanlar）in kritik hammadelerden biridir。因此，烟草磷酸四氢丝氨酸的脱水时间约为1m。在这种钙中，通过应用含钙的物理化合物选择性地分离出磷酸盐cevic的分离的碳矿物（钙和文石）。calimada中使用的天花板特性由X轴衍射（XRD）、热重（TG）和X轴荧光（XRF）光谱仪定义。测量计算速率（750、850和900˚C）和表面效应（15、30、60、90和120 dk）。Saccharioz的软骨线（0、150、300、450 dev/dk）和lic表面（0、0.25、0.50、1、1.50和2M）的作用在lic岛中表现出来。因此即使二氧化碳含量很高，钙也不会从天花板上去除，循环中也不需要二氧化碳矿物质。

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.
