Abstract
Embodiments of the present invention provide systems and methods for efficiently producing both a low-pressure ozone stream and high-pressure oxygen stream using a single air separation unit. The low-pressure ozone stream and high-pressure oxygen stream can be produced with significant energy savings and can be used in variety of applications, including the extraction of precious metals from ore with aqueous oxidation reactors and high-pressure oxidation reactors.
