Integration assessment of the hybrid sulphur cycle with a copper production plant

• Hybrid sulphur cycle for in-situ supply of hydrogen and oxygen to copper plant. Process models a refinery the hybrid in Aspen Plus. Techno-economics green refinery. Potential lower carbon dioxide emissions from production Copper is third-most widely-used metal worldwide. However, processing an energy-intensive process consuming large quantities fossil fuels, both as reducing agent energy which contributes significantly anthropogenic emissions. The combines concentrating solar thermal with electrolysis offer strong potential low-cost production. A preliminary evaluation reported techno-economic this displace current fossil-based sources integrated mine (cradle-to-gate approach) at remote location Australia excellent resource. effect ore composition on integration plant evaluated using developed evaluations show that sizing meet demand refining more techno-economically viable than required replace fuel process. Moreover, it has been found decrease dixoide operational expenditure refineries ores sufficiently high sulphide content (?50% mass fraction).
