Abstract: A photocatalytic batch reactor can include a reactor vessel configured to receive a photocatalyst, the housing having an inlet, an outlet, and an opening configured to allow light to pass into the interior volume. The photocatalytic batch reactor can include a carbon-dioxide pump that is configured to pressurize carbon-dioxide en route to the reactor vessel. The photocatalytic batch reactor is operable in a gas state in which gas carbon-dioxide is supplied to the reactor vessel from a gas carbon-dioxide container. The photocatalytic batch reactor is also operable in a liquid state in which liquid carbon-dioxide is supplied to the reactor vessel from a liquid carbon-dioxide container. The photocatalytic batch reactor is also operable in a supercritical state, in which supercritical carbon-dioxide is supplied via the carbon-dioxide pump.

Abstract: A method of recovering gold from a metal combination includes contacting the metal combination with a first leaching liquid sufficient to oxidize one or more additional metals of the metal combination to produce an oxidized product liquid and a recovered gold product, wherein the first leaching liquid includes chloride ions.
