A dry method of removing pyrite from mineral coal in which the coal is milldried in a milling gas stream and the milled product is subjected to classification to recover a predominantly coal combustible fine fraction and a gravel or coarse fraction containing mining detritus, pyrite and coal. The gravel or coarse fraction, according to the invention, is subjected to density separation in ...

a means to increase coal fineness and/or throughput (Figure 2). This mill retrofit goes well beyond the improvements achievable with stationary classifier retrofits, especially when 80+%/200 fineness is required. Rotating classifier pressure drop is lower than that of stationary classifiers. In addition, grinding zone pressure

Glossary of Mining Terminology. A. Abutment In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ...

The coal mining waste consist of three fractions, rich in pyrite, rich in clay minerals and rich in carbon [6].In addition to iron and sulfur, the XRF chemical analysis (Table 1), in agreement with the Xray diffractogram (Fig. 1 a), shows that coarse pyrite has quartz (SiO 2) and calcite contamination (CaCO 3, which decomposes into CaO + CO 2) and the other oxides of clay minerals origin ...

Iron in coal is primarily associated with aluminosilicate clays and pyrites. Coal deposits with high pyrite content contain appreciable amounts of both massive and finegrained pyrites which are primarily differentiated by the size of the mineralization [23]. While massive pyrite can be removed from the coal by washing, the framboidal pyrites,

The data on study of intra and interseam and regional interfield variation of sulphur is very limited mainly done and generated by Chandra et al. (1980a, 1983) on the Tertiary coals of Arunachal Pradesh, Assam, and Meghalaya in India. According to them megascopic pyrites occur mostly as patches in bright and semibright coals (Fig. ).These normally fill small fractures and occur as ...
