Leaching Behavior of Fly Ashes from Power Plants
Leaching Behavior of Fly Ashes from Power Plants
摘要
Abstract
The Yanzhou mine district, located in southwestern Shandong Province, is about 1300 km2 with more than 8×109 tons of proved coal reserves and there are 10 big power plants in this area. A large amount of coal ashes, which are regarded as waste materials, have been stockpiled in the area and have influenced the environment of the mine district. In this paper, analysis of fly ash samples from three power plants is carried out, the enrichment and concentration of trace elements, Pb, Zn, Cu and As, in coal ashes are analyzed, and petrological and mineralogical characteristics and chemical compositions of coal ashes are studied. The aim of this work is to provide basic scientific data for utilization of ashes and reduction of environmental pollutions.关键词
