Copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. These methods avoid traditional mining methods of digging, moving and disposing of large amounts of rock. ...
Extracts from the answers: Phytomining. The copper ions can then be leached (dissolved) from the ash by adding sulfuric acid.This produces a solution (leachate) of copper sulfate. Pure copper metal can then be extracted from this solution by electrolysis or displacement using scrap iron.. Bioleaching

What is phytomining? This process takes advantage of how some plants absorb metals through their roots The plants are grown in areas known to contain metals of interest in the soil; As the plants grow the metals are taken up through the plants vascular system and become concentrated in specific parts such as their shoots and leaves These parts of the plant are …
Phytomining can be used to supplement cadmium mining, for example, but has yet to produce economically viable yields.
