recovery/recycle option is possible, the targeted metal is recovered by suitable chemical
leaching, separation, and purification methods and the residue is treated to immobilize the
remaining contaminants to make them acceptable for landfill disposal. Where either and/or
economic reasons prevent a recovery/recycle route, the waste is treated to immobilize the
contaminant process. Basically, the Hydromet's immobilization process involves the addition
of chemical reagents to convert all of the metal constituents into extremely insoluble
compounds.
