Abstract
A process for oxidation of ferrous ions in solution, and more particularly a process for improved base metal and/or uranium leaching from ores, concentrates or tailings using ferric ion as an oxidising agent. A reaction vessel (10) holds a ferrous ion-containing solution, for example, a copper sulphide leach slurry or concentrate. An agitator (12) may be provided to promote leaching of the base metal into solu-tion. Some of the ferrous ion-containing solu-tion is drawn off from the reaction vessel (10) and pumped through an in-line mixer (14) via a feed pump (16). Oxygen is injected into the reactor (14) to facilitate oxidation of the fer-rous sulphate to form ferric sulphate. The fer-ric ion-containing solution is then recirculated back to the reaction vessel (10) where the fer-ric ions arc reused in the dissolution of copper sulphide into soluble copper sulphate. The two processes of ferrous oxidation and metal leach-ing can be conducted either simultaneously or sequentially to effect recovery of copper, other base metals or uranium from ores, concentrates or tailings.
