A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister copper may be refined to cathode ...

Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …
