What are the main advantages of using phytomining and bioleaching over traditional mining methods?

The main advantages of phytomining and bioleaching include reduced environmental disruption, lower energy requirements, and the ability to extract metals from low-grade ores. These methods also prevent the generation of large amounts of waste rock, making them more sustainable.

A strong answer should directly address the approved learning objective to compare phytomining and bioleaching with traditional mining in terms of moving and disposing of rock. (HT only). This question belongs to Alternative methods of extracting metals within Using the Earth's resources and obtaining potable water, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to HT only, and keeps the wording specific to AQA GCSE revision.
