Abstract

In this study, mineral matter contents of Tufanbeyli lignite samples were investigated by X-ray diffraction (XRD) technique. The X-ray diffractograms of the original lignite samples were evaluated using the SIROQUANT software operating with the Rietveld method. The minerals and their quantities in the crystalline form in the mineral matter were determined. The extraction (leaching) method was used to determine the amount of inorganic substances in the amorphous form, which constitutes a significant portion of the total mineral content. Quartz, calcite, aragonite, illite, illite/smectite, montmorillonite, goethite and pyrite minerals were found in varying amounts in the samples. Most of the mineral content of lignite samples is soluble in water and acids.

Tufanbeyli Linyitlerinin Mineral Madde İçeriğinin İnteraktive Rietveld Temelli X-Işını Difraksiyonu Yöntemi ile Kantitatif Olarak İncelenmesi

Abstract

Bu çalışmada, Tufanbeyli linyit numunelerinin mineral madde içerikleri X-ışını difraksiyon (XRD) tekniği ile incelenmiştir. Orijinal linyit numunelerinin X-ışını difraktogram çekimleri Rietveld yöntemi ile çalışan SIROQUANT yazılımı kullanılarak değerlendirilmiş ve mineral madde içerisindeki kristal formdaki mineraller ve bunlarım miktarları belirlenmiştir. Toplam mineral madde miktarının önemli bir kısmını oluşturan ve amorf formdaki inorganik maddelerin miktarını belirlemek için özütleme (liç) yöntemi kullanılmıştır. Numunelerde değişen miktarlarda kuvars, kalsit, aragonit, illit, illit/smektit, montmorillonit, götit ve pirit minerallerine rastlanılmıştır. Linyit numunelerinin mineral madde miktarının büyük bir kısmını suda ve asitlerde çözülebilen inorganikler oluşturmaktadır.
