BBC - GCSE Bitesize: The future of copperThis method of extraction is called phytomining. Some bacteria absorb copper compounds. They then produce solutions called leachates, which contain copper compounds. This method of extraction is called bioleaching. Copper can also be extracted from solutions of copper salts using scrap iron. Iron is more reactive than.the process of phytomining of copper,GCSE CHEMISTRY - Extraction of Copper - Thermal Decomposition .Phytomining. Some plants absorb metal compounds (including copper) when they grow. The plants can then be burned and the metal is extracted from the ash. The process is called phytomining and it can also be used to extract metals from contaminated land. Brassicas (the cabbage family) can extract metals including.
