Copper Extraction from Sungun Mine Concentrate: A Comparative Assessment of Conventional and Baking-Assisted Leaching Methods

This study compares the efficiency of four methods for copper extraction from Sungun sulfide concentrate: conventional acid leaching, oxidant leaching, basic baking followed by acid leaching, and acid baking followed by water leaching. The results show that acid and oxidant leaching yield limited copper dissolution due to the stability of sulfide minerals. Basic baking improves extraction but remains constrained by incomplete solid-phase reactions. Acid baking provides the highest efficiency, converting sulfide phases into soluble sulfates with optimal acid consumption. Overall, acid baking is identified as the most effective and economical method for copper extraction from the Sungun concentrate.
