摘要: Leaching column experiments were conducted on sulfide-bearing mine waste material to evaluate the efficacy of transformed red mud (TRM) derived from bauxite refining residue, zero-valent iron, and synthetic iron (III) hydroxides in reducing contaminant mobility. Wastes placed columns together with sorbents/reagents three different setups: as a blended amendment (mixing method), bed at bottom (filtration or combination two previous methods. Results showed that filtration methods are most effective, whilst use amendments leads unsatisfactory results, because selective removal.
