How can plants help to exploit low grade metal ores?

Answer 1

Plants can help exploit low-grade metal ores through a process known as phytomining, where certain plants absorb metal ions from the soil and concentrate them in their tissues. These plants can then be harvested and processed to extract the metals, providing an environmentally friendly and cost-effective alternative to traditional mining methods. Additionally, phytoremediation can help to rehabilitate contaminated mining sites by stabilizing heavy metals and improving soil quality, making it easier to access residual metals in the future. This approach not only enhances metal recovery but also promotes sustainable land management.
