“…Since data on trace elements in coal are very limited in India and especially not available for Gondwana coals in the Extrapeninsular region, we have tried to make some comparison with the data available for the Lower Gondwana coals in the peninsular region (Table 5). For this the data from the Barakar Formation is taken (Mukherjee et al 1988). The trace element data we generated are based on standard ASTM procedure and are presented with respect to coal in contrast to the data generated by Mukherjee et al (1988) that are presented with respect to total ash content.…”

“…However, this type of study is rather limited in India. Though some work has been done primarily by the Geological Survey of India (Mukherjee et al 1982 and the references therein; Mukherjee et al 1988Mukherjee et al , 1992 and Regional Research Laboratory (now Institute of Minerals and Materials Technology), Bhubaneswar (Mohanty et al 2006), the Gondwana coals of the Himalayas have not been investigated in respect of their trace element/metal content.…”

Lower Gondwana coal from Garu-Gensi area in the West Siang district of Arunachal Pradesh in the Eastern Himalayas have been characterized with respect to their maceral constituents, mineral matter, ash composition, sulphurand trace-element contents. These are low-rank bituminous coals (V 0 = 0.64) and their vitrinite content is about 60%. A first hand data with respect to twenty one trace-elements are reported. Our data indicate that these Lower Gondwana coals of extra-peninsular region are richer in terms of their trace-element content when compared with their counter parts of peninsular India.

“…Therefore, it is inferred that Ni shows dual affinity. Singh et al (1983) and Mukherjee et al (1988) observed negative relationship for Ni with ash content and argued in favour of its affinity towards organic fractions in lower Gondwana coals in India. Swaine (1980) also concluded that there is enough evidence in support to link Ni with organic constituents although Swaine (1995) indicated that Ni might be associated with both the organic and inorganic components of coal.…”

“…Thus, the interest on coal research in our country has been growing widely. The quantitative data on trace elements of various Gondwana coal (Mukherjee et al 1981(Mukherjee et al , 1988Singh et al 1983;Pareek and Bardhan 1985;Mohanty et al 2001) and Tertiary coals (Mukherjee et al 1981;Mukherjee and Srivastava 2005;Baruah et al 2003;Sahoo et al 2014) are available. However very few data on the modes of occurrence of trace elements are available in the West Bokaro coalfield, which is one of biggest Gondwana coalfields based on its areal extent, number and thickness of coal seams and reserves of coking coals (Pareek and Bardhan 1985).…”

The mineralogy and trace element contents in coals from the West Bokaro coalfield, which is the one of the biggest Gondwana coalfields of India, were studied to delineate enrichment of trace elements and their modes of occurrence. Elemental concentrations with reference to their crustal abundances indicated that coals are relatively enriched in As (4.4-15.5 mg/kg), Cd (0.3-3.0 mg/kg), Cu (28.0-68.1 mg/kg) and V (46.6-178.0 mg/kg); depleted in Co (10.8-28.4 mg/ kg), Mn (7.6-483.4 mg/kg), Ni (13.0-31.6 mg/kg), Cr (14.2-85.5 mg/kg) and Zn (5.25-70.4 mg/kg). The concentration of As, Cd, Co, Cu and V were higher than the average values of world and Indian coals. Mineralogical study carried out by X-ray diffraction shows that quartz and kaolinite occur as dominant mineral phases in this coal. Fourier transform infrared spectroscopy pattern suggests organic structures primarily containing aromatic nuclei, aliphatic side chain and some oxygen containing groups. The modes of occurrence of trace elements present in these coals have been determined through statistical approach. Both Cu and Cr are more closely associated with mineral matter, whereas Co is dominantly present with its organic form. The concentrations of Cd, Mn, Ni, Zn, As and V have apparently occur in both organic and inorganic constituents. This study would be helpful to assess the potential environmental impacts during mining and combustion of this coal.
