摘要
The deashing effects of fluoride-bearing acid on coal for the producing high pure coal are studied. the effects of several factors on deashing ratios of coal are also investigated. The results show that fluoride-bearing acids are efficient deashing agents of coal and can effectively leach out almost all mineral components in coal.
