into two piles, one for bioleaching and the other for phytomining. Involves bacteria. Extracts metals from slag heaps, contaminated ground and low grade ore. This method has a low yield. This method takes a long time – up to two years. The process is made more efficient by controlling conditions such as pH, temperature.

purification of copper by electrolysis metal extraction reduction of .

Finite reserves of copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing.

Phytoremediation - Wikipedia

After harvest, a lower level of the contaminant will remain in the soil, so the growth/harvest cycle must usually be repeated through several crops to achieve a significant cleanup. After the process, the cleaned soil can support other vegetation. Mining of these extracted metals through phytomining, is also being experimented.
