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

1. Plants are grown in metal-rich soil. 2. Plant is burned to form ash containing lots of metal oxide 3. Ash is mixed with an acid, heated gently so it can react (leeching) 4. Filter ash from solution 5. Displacement reaction and/or electrolysis so we can get pure metal Doesn't damage the environment and can extract metal from low-grade ore
