Copper Mining and Processing: Processing of Copper Ores ,Caustic Roasting and Leaching of Electric Arc Furnace Dust

A Processing of Oxide Ore 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 electrowinningIn the subsequent dilute caustic leaching process both the zincite (ZnO) and the sodium zincate were soluble and the hematite was relatively insoluble After roasting and leaching, the zinc recovery was found to be about 95%, while the majority of the iron oxide remained in the leach residue.
