PRECIOUS METAL RECOVERY USING UV OZONE

摘要

A method for recovering precious metals from ore is disclosed. Ore is treated in an acidic slurry with an activated oxygen mixture obtained from an ultraviolet light ozone generator. The activated oxygen frees chemically bonded precious metals creating an expanded, hydrated ore so that the metals may be oxidized and leached out using standard leaching techniques. In addition, the activated oxygen aids in the leaching process. Substantial increases in the amount of precious metal recovered from a given amount of ore result.
