The widespread presence of trace elements is shown by reviewing their roles during the mining, beneficiation and combustion of coal and during metal mining and treatments. Special attention is given to Hg, to the environmentally important mineral, py

Relevant published information is reviewed and assessed for the effects of mining and beneficiation on trace elements in coal. In general, the concentrations of those elements associated with mineral matter are decreased to varying degrees depending

The concentration of boron in Australian and Canadian coals determined using atomic emission spectrometry (AES), inductively coupled plasma spectrometry (ICP-AES) and prompt gamma-ray spectrometry is summarized in order to assess the variation of B c

This is partly a review and partly the results of some experimental work. Results for concentrations of trace elements in samples of coal from 9 mines in about 100 km of one seam show the variability in terms of variance ratios, namely, maximum divid

Fluorine was determined in 57 samples of coals from western Canada and the Yukon (47 bituminous, 4 subbituminous, 6 lignite) by a pyrohydrolysis method. The range of values is 31–930 ppmw F in dry coal, the lowest values being mainly for the low-ra

Various aspects of the organic association of trace elements in coals are reviewed. For estimating organic affinity, reference is made to float-sink methods, the relationship between trace-element content and ash yield, and mild extraction. Carboxyli

Much has been written about flyash probably mainly because it is the most important by-product of the combustion of coal. During and after combustion, trace elements in the coal are redistributed into the vapour phase, bottom ash and flyash (Figure 1

Trace elements in the atmosphere are mostly associated with particulates, although there may be some in the gaseous phase. There are diverse sources, natural and anthropogenic. Amongst natural sources are the weathering of rocks and soils, volcanism,
