Slide 12: Potential average annual production rates
Based on the Case 2 model and assuming 85% For personal use only recoveries and a twenty year mine life , the following average annual production rates are possible for Copper Hill: Copper: 15 to 20,000 tonnes p.a. Gold: 50 to 60,000 ounces p.a. Sulphur: 158,000 tonnes p.a. With potential Acid produ
Slide 13: Maximising Value
铜山 Maximising Value For personal use only • By producing copper metal, bullion gold, sulphuric acid and iron granules • Higher value products with minimal waste and greatly improved environmental outcomes
Slide 14: Existing Technologies will be used
Copper 铜山 Hill For personal use only Existing Technologies will be used. On-site: Crushing-Grinding-Flotation At Port Pirie: Roaster-Acid Plant then Copper by SW-EW Gold by CIP/CIL All aspects of this proposal will use ‘off-the shelf’, conventional processes.
Slide 15: Maximising Value: roasting of sulphides
铜山 Maximising Value For personal use only • Roasting of Copper Hill sulphides (CuFeS2 and FeS2) produces a calcine from which the copper and gold would be leached with sulphuric acid from the sulphur dioxide (SO2) exhaust gas to produce cathode copper (SX/EW) and bullion gold by CIP/CIL at maximum r
