Studi Karakteristik Mineral Pirit Pada Batubara Berdasarkan Hasil Analisis Mikroskopi, Proksimat, Sulfur Total, Dan X-Ray Difraction

Abstract: Mineral pirit merupakan salah satu mineral sulfida yang sangat sering dijumpai di dalam batubara. Kehadiran mineral pirit sangat berpotensi menimbulkan masalah pada kegiatan penambangan dan pemanfaatan batubara. Terkhusus pada kegiatan penambangan, mineral pirit berpotensi menimbulkan air asam tambang (acid mine drainage) dan pada pemanfaatannya menimbulkan dampak negatif terhadap lingkungan. Permasalahan tersebut melatarbelakangi penulis untuk melakukan kegiatan penelitian dan analisis terhadap karakteristik … Show more

“…Microscopic observations are made to determine the morphology and mineral forms found in coal samples [3]. This method is based on a detailed microscopic examination of polished parts of coal; in principle, observing some of its optical properties, such as morphology, reflectance, refractive index, and anisotropy, allows the identification of a type of mineral [13], observations of mineral appearances in coal are carried out using a microscope with a scale of 100μm.…”

“…Ash content in coal is a representation of the minerals contained in coal [16]. The higher the mineral content in coal, the higher the ash content [3]. Ash content ranged from 8.8 to 40.2% indicating a medium-high category [18], low ash 0% -8% and high ash (> 15%) [22].…”

“…The quality of South Sulawesi's coal is still relatively low and mostly used for additional fuel in cement factories and some local industries. South Sulawesi coal is spread in several districts [2][3][4][5][6][7][8], one of which is located in Barru Regency. One of the locations for coal deposits in Barru Regency is in the Paludda Region, Pujananting District.…”

“…Physical, chemical, and biological methods may be used to decrease the sulfur content in high sulfur coals [1][2][3]. Sulfur analyses have also been conducted to study many coals from different areas and country [4]; [5]; [6]; [7]; [8]; [9]; [10]; [11]; [12]; [13]; [14]; [15]; [16]; [17]. One of the most common technologies used for fine coal beneficiation is flotation [18].…”
