ABSTRACT:
A method for treating arsenic-containing waste materials for disposal in landfill sites comprises admixing an arsenic waste, Portland cement, sand, one or more water-soluble manganese or alkaline earth metal salts, and water, thereby producing a slurry similar to wet concrete, which slurry, when cured, leaves a rock-like material containing entrapped arsenic. This material may be used for landfill without danger of ground or rain waters leaching arsenic therefrom.
