ABSTRACT:
Heavy metals are removed from paint chips by leaching with an aqueous acid. Heavy metals are also efficiently removed from contaminated soil by a process which comprises leaching or washing the soil with a mild leachant solution comprised of an aqueous solution of an acid and a salt. The heavy metals are recovered from the leachant by cementation.
