Extraction of Metals. The History of Metals.. Metals have been used by people for many thousands of years. Gold and silver, found as native metal, were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age but gold and silver are too soft to be used as tools.. The first really useful metal to be discovered was bronze. ...

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 …
