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 …
