Abstract

The element oxides or minerals that are found in coal can be classified into koalinite, quartz, siderite, hematite, etc. The effects of these element oxides or mineral matter during gravity fractionation were studied. The float and sink methods and sieving were employed to partition the ground coal. The principal techniques include LAT using quantitative evaluation of X-ray diffraction; HAT for conventional geochemical analysis; and knowing the morphological structures and elemental compositions with the help of Fe-SEM and EDS. Kaolinite was recorded at (31.38–33.23%) high at heavier gravity fractions and at low concentrations (7.38–14.08%) at lower gravity fractions. Quartz ranged from 24.16 to 32.36% in heavier gravity fractions and from 5.79 to 12.33% in lower gravity fractions. Sanidine (AlSi3O8) was reported at 21.4% in the heavy fraction. The behaviour of four elements, Ca, Al, Fe, and K, was reported at around 1.1-2.0 mg/kg in heavy gravity fraction after removing these at around 0.01 to 0.41 mg/kg. It was probably derived from the interaction of organically-associated coals during the low-temperature ashing process, but in lower fractions, it was recorded at a trace level. There are almost 3 to 4 times the separation noted for most of the obstacle elemental oxides
