GCSE CHEMISTRY Extraction of Copper Thermal

Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copperII oxide and copperII sulfide. CopperII oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1 copper but they are still used because copper is so valuable.
