An apparatus for recovering a target metal from an article. The apparatus includes a reaction chamber defining an interior space; an evaporator coupled to the reaction chamber, a condenser within the reaction chamber, and a solution recovery portion within the reaction chamber and separate from the evaporator. With the apparatus, an oxidizing solution is converted into a vaporized oxidizer; the article is exposed to the vaporized oxidizer for interaction with the target metal; the vaporized oxidizer is condensed into a condensed solution that removes the target metal from the article; and a concentrated solution comprising the condensed solution and the target metal is collected separate from the oxidizing solution. After the concentrated solution is collected, the target metal can be separated therefrom through any number of known processes.
