Abstract
A process is provided by which dissolved metals may be recovered from aqueous waste solutions and converted to a particulate material, which may in turn be used as a filler for products such as asphalt. The process involves effecting reaction in the solution to produce a sludge comprised of metal hydroxides and sulfides, and admixing lime with a concentrate thereof to ultimately produce the filler.
