Phytomining. Phytomining uses plants. In order to extract copper, phytomining uses plants to absorb copper compounds from the ground. The copper compounds from the soil builds up in the cells of the plant. Plants can be burnt to release copper. In order to release the copper compounds from the cells of the plant, the plants are harvested and burnt.
