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. Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below).
