Leaching gold and palladium with aqueous ozone
A study of ozone based leaching in dilute chloride media as a route to precious metal recovery.
Recovering precious metals from ores and secondary sources usually depends on leaching. The choice of oxidant and solution chemistry determines the rate, selectivity and environmental burden of the process.
The study examines aqueous ozone in dilute chloride media for gold and palladium. It looks at how the metals dissolve and what conditions favour recovery, with an eye on a process that avoids more aggressive reagents.
