Compare phytomining and bioleaching with traditional mining in terms of moving and disposing of rock. (HT only)

In the subtopic Alternative methods of extracting metals, this learning objective focuses on compare phytomining and bioleaching with traditional mining in terms of moving and disposing of rock. (HT only). Within Using the Earth's resources and obtaining potable water, students should explain this idea in the exact curriculum context rather than as an isolated fact. Approved keywords for this objective include HT only, phytomining, and bioleaching. phytomining means a method of extracting metal compounds from soil using plants that absorb these compounds. Avoid students often confuse phytomining and bioleaching with traditional mining methods, thinking they are the same; instead to fix this, students should focus on the differences: phytomining uses plants to absorb metals, while bioleaching uses bacteria, both of which are less invasive compared to traditional mining that involves moving large amounts of rock. For exam answers, compare the environmental impact of phytomining and bioleaching with traditional mining methods, focusing on rock movement and disposal.
