NTE (Nadir Toprak Elementleri + Y) ve Sc, enerji sektörü ve elektronik gibi yüksek teknoloji gerektiren alanlar için küresel olarak ihtiyaç duyulan stratejik malzemelerdir. Kömürler, bileşimlerinde birçok eser element ile birlikte Nadir Toprak Elementleri içerir. Son yıllarda, NTE'nin küresel talep ve arzı arasındaki uçurum arttıkça, özellikle bu malzemelerin ithalatına büyük ölçüde bağımlı olan ülkeler için alternatif kaynak arayışları giderek daha önemli hale gelmiştir. Özellikle atık madde olarak değerlendirilen kömür ve kömür külü, NTE dahil birçok element için olası bir kaynak olarak kabul edilmektedir. Bu çalışmada incelenen Türk düşük dereceli kömürleri (kuru tam kömür bazında) ortalama 73,73 ppm kritik mineral bolluğuna sahiptir. Türkiye'deki çeşitli Neojen kömür yataklarından toplanan materyallerin, diğer örneklere göre nispeten daha yüksek miktarda NTE (>100 ppm) içerdiği bulunmuştur, bu durum, kömür damarlarının ilişkili sedimanter birimlerin volkaniklastik özelliğine atfedilebilir. Bu çalışmada incelenen kömürlerin kritik mineral içerikleri Türk, Dünya, ABD ve Çin kömürlerine göre daha yüksek olmasına rağmen üretim açısından ekonomik olmadığı ve üretim tekniklerinin geliştirilmesi ile dikkate alınabileceği tespit edilmiştir.

A NON-TRADITIONAL RESOURCE FOR CRITICAL MINERALS; RARE EARTHS (REY+Sc) CONTENTS OF SOME TURKISH LOW RANK COALS

Yıl 2022, Cilt 25, Sayı 2, 155 - 172, 03.06.2022

REY (Rare Earth Elements + Y) and Sc are strategic materials that are needed globally for areas requiring high technology such as the energy sector and electronics. Coals contain Rare Earth Elements along with many trace elements in their composition. In recent years, as the gap between REE's global demand and supply increases, the search for alternative sources has become increasingly important, especially for countries that depend heavily on imports of these materials. Particularly considered as waste material, coal and coal ash are considered a possible source for many elements, including REE. Turkish low-rank coals analyzed in this study have an average critical mineral abundance of 73.73 ppm (on a dry whole coal basis). Materials collected from the various Neogene coal fields in Turkey were found to contain a relatively higher amount of REY (>100 ppm) relative to the rest of the samples, which may be attributed to the volcaniclastic character of the sediment associated with the seams. In this study, it was determined that although the critical mineral contents of the investigated coals were higher than Turkish, World, USA, and China coals, they were not economic for production and could be taken into consideration by the development of production techniques.
