Abstract
A process for oxidizing a metal from a lower valence state to a higher valence state comprises contacting the metal, usually contained in a solution, with a sufficient amount of an oxygen-containing gas to provide at least about 300% excess of stoichiometric oxygen with respect to the metal at the lower valence state. The metals are preferably used as chelated solutions thereof. Some of the representative metals are iron, copper, manganese, lead or mercury.
