Abstract
A method of treating an aqueous cyanide- and/or complexing-agent-containing solution, including high-temperature treating the solution in a closed reaction vessel, discharging at least a portion of the treated solution from the reaction vessel, at least partially replacing the discharged fraction with untreated solution, and subjecting the untreated solution to high-temperature treatment along with a treated-solution fraction remaining in the reaction vessel.
