GCSE CHEMISTRY Extraction of Copper Thermal

2017-3-27  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).

2018-7-20  Simply put,PHYTOMINING is a form of EXTRACTION. What does it do? It extracts COPPER COMPOUNDS from the ASH of a burnt plant. By burning . the plant, the oxygen is reacting with copper. This makes COPPER OXIDE . The ash which contains the copper compound is then put through ELECTROLYSIS. How do these compounds get into the plant?
