How does phytomining work? 1. Plants have the ability to take up the copper from the ore and put it in their body tissue 2. You burn the plants 3. The ash contains copper copper taken by electrolysis Bioleaching 1. bacteria can grow on the ore produce solution as a by product of growing on there. 2. Solution goes through electrolysis
