AbstractThe coal-washing rate in China increased from 1991 to 2014 and shows a particular increase from-22% to -60% since 2002. However, few studies pay attention to the use and disposal of the coal-washing byproducts (CWBs). A preliminary estimate of the likely S, As, F and Hg contents and emissions from the combustion of CWBs in China was determined in this work. About 632 million tons of CWBs, including middling coal, flotation tailing coal and coal slime, were produced in China in 2014. About 4.03%, 20.80%, 1.48%, and 73.25% CWBs were used for thermal power, industry, domestic and discard. The mean S, As, F and Hg contents of CWBs are 1.52%, 14.04 mg/kg, 21631 mg/kg and 0.27 mg/kg, respectively. SO2 emissions in 2014 from the combustion of CWBs were-5.76 million tons, similar to that released into the atmosphere by China's coal-fired power plants, accounting for-29% of the country's total SO2 emissions. Arsenic, F and Hg emissions from CWBs were 1 599.54, 61 575.07 and 77.16 tons, respectively. These emissions have become a critical component of air pollution in China. (C) 2016 Elsevier Ltd.
