Mining industry waste remediated for recycle by vitrification
Characteristically hazardous waste water treatment sludges from a U.S. mining company were considered a long term liability since stabilization via a cement wasteform would not provide the stringent leachant concentrations for an EPA acceptable recycle product. Vitrification of the sludges into three different types of glass at elevated temperatures provided recyclable products. The use of treated materials containing hazardous metals has been previously considered by the EPA for residues remaining from High Temperature Metal Recovery (HTMR) operations. These treated materials could be used for recycling as (1) covered sub-base materials (e.g., in construction of paved roads, parking lots, and driveways), (2) additive ingredients in cement or concrete/asphalt mixtures, (3) top grade or surfacing materials, e.g., in construction of roads, parking lots, and driveways (glassphalt or glasscrete), and as anti-skid/de-icing materials. The glass waste forms provide a 87-93 percent volume reduction compared to alternative stabilization in cement and provide for recycle.
