The Mining Waste web-based document identifies and evaluates emerging and innovative technologies that can cost-effectively and successfully be used to characterize, remove, treat, reuse, or stabilize mining, milling, processing, and smelting wastes and mining-impacted water. The document also addresses state or federal regulatory obstacles to deployment of conventional or innovative environmental technologies at mine-impacted properties and approaches and/or solutions to overcome regulatory barriers.
BCRs are engineered treatment systems that use an organic substrate to drive microbial and chemical reactions to reduce concentrations of metals, acidity, and sulfate in MIWs. While this chemistry is fairly well understood, much has been learned over the last 20 years on how to improve the effectiveness, maintain hydraulic permeability, and ensure longevity of the systems.
