Evaluation of Leachates from Coal Refuse Blended with Fly Ash at Different Rates

ABSTRACT There is great interest in returning coal combustion products to mining sites for beneficial reuse as liming agents. A column study examined the effects of blending two coal fly ashes with an acid‐forming coal refuse (4% pyritic S). Both fly ashes were net alkaline, but had relatively low n...
