Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copper(II) oxide and copper(II) sulfide. Copper(II) 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.

Biological Methods of Extracting Metals

Phytomining is the process of using plants to extract copper from low grade ores in the ground. Firstly, areas of land must be found that contain a high concentration of low grade copper ores. Once found, plants are planted on this land and allowed to grow.. As the plants grow they absorb minerals from the ground in which they are growing. This process causes copper compounds …
