Turning Copper Ore into Copper: What are the Processes?

After the ore is crushed to powder, it is treated with froth flotation, whereby the powder reacts with reagents that treat the copper to make it hydrophobic. After being treated further with water and a ing agent, frothing is enhanced. After the air is brought up through the water, bubbles form that float the water-repellent copper ...

The Extraction of Copper

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
