Lesson Title: Today we are learning about
How can we extract metals from low grade ores?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. The Earth?s resources of metal ores are limited.
  2. Copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching.
  3. These methods avoid traditional mining methods of digging, moving and disposing of large amounts of rock.
  4. Phytomining uses plants to absorb metal compounds. The plants are harvested and then burned to produce ash that contains metal compounds.
  5. Bioleaching uses bacteria to produce leachate solutions that contain metal compounds.
  6. The metal compounds can be processed to obtain the metal. For example, copper can be obtained from solutions of copper compounds by displacement using scrap iron or by electrolysis.
  7. Students should be able to evaluate alternative biological methods of metal extraction, given appropriate information.

Keywords:
  • Electrolysis: Chemical decomposition produced by passing an electric current through a liquid or solution containing ions. (1)
  • Bioleaching: Extraction of metals from their ores through the use of living organisms. (1)
  • Phytomining: The planting (and subsequent harvesting) of vegetation that will selectively concentrate specific metals from the soil into their tissues. (1)
  • Ore: A naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. (1)

AFL/Key Questions:
  1. What will happen to the Earth's supplies of metal ores if we continue to extract them at the rate we are now?
    The Earth's resources of metal ores are limited. Eventually they will run out.
  2. What are new ways of extracting copper from low-grade ores called?
    Copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching.
  3. What do these new methods of copper extraction avoid?
    These methods avoid traditional mining methods of digging, moving and disposing of large amounts of rock.
  4. How is phytomining carried out?
    Phytomining uses plants to absorb metal compounds. The plants are harvested and then burned to produce ash that contains metal compounds.
  5. How is bioleaching carried out?
    Bioleaching uses bacteria to produce leachate solutions that contain metal compounds.
  6. How can copper compounds be processed to obtain the metal.
    The metal compounds can be processed to obtain the metal. For example, copper can be obtained from solutions of copper compounds by displacement using scrap iron or by electrolysis.
