Innovations Introduction to Copper Mining ExtractionHow is copper extracted from malachite ore Quora
The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals Such ores originate from sulfur bearing volcanic magmas which have separated into metal sulfides and siliceous meltsCopper is leached with sulfuric acid from crushed oxide based or The refined copper from this process is classified as SXEW Solvent Extraction ElectroWon I visited a copper mine in Arizona where this process was used Crushed ore is sp
