Describe bioleaching as using bacteria to produce leachate solutions containing metal compounds. (HT only)

In the subtopic Alternative methods of extracting metals, this learning objective focuses on describe bioleaching as using bacteria to produce leachate solutions containing metal compounds. (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, bioleaching, leachate, and metal compound. bioleaching means a process that uses bacteria to extract metal compounds from ores, producing leachate solutions. Avoid students often confuse bioleaching with traditional mining methods, thinking they are the same process; instead emphasize that bioleaching uses bacteria to produce leachate solutions containing metal compounds, while traditional mining involves physically extracting ores from the earth. For exam answers, make sure to explain how bacteria are used in bioleaching to produce leachate solutions that contain metal compounds.
