<p>This invention is an aqueous leaching solution containing an oxidizing agent and a chelating agent. It is used to leach metal values from metal chalogenide minerals, including metal sulfides and methal sulfide-like minerals, as found in certain rock matrices, such as ores, mineral concentrates, and mine waste materials. The leach solution is used at ambient temperature and a near-neutral pH. It provides superior solubilization of metal values from metal chalcogenide minerals.</p> |
