Abstract:
There is provided a method for leach extraction of copper/iron/sulphur ores and concentrates including leaching the mineral with an aqueous stream containing ferric ions and sulphuric acid in the presence of oxygen, the aqueous stream including a solution formed by reaction of basic ferric sulphate with excess suphuric acid. Integrated methods of forming and releaching basic ferric sulphate are also described.
