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 melts

Metal ores are a finite resource which are in limited supply New methods of copper extraction exploit waste ores and low grade ores Phytomining involves growing plants on top of low grade ores The plants absorb copper ions through their roots The plants are then burnt to ashes containing copper ions These ions are leached from the ash using sulfuric acid

This is a common extraction process for the more reactive metals for example, for aluminium and metals above it in the electrochemical series You may also come across it in other cases such as one method of extracting copper and in the purification of copper
