  1. Chapter 16: Mineral Resources and Mining Mr. Manskopf Notes also at http://www.manskopf.com

  2. MAIN IDEA Modern societies depend upon a large number of a variety of minerals. Mining of those minerals has a great impact on our environment.

  3. GOALS for Chapter 16 Notes • Investigate what minerals are, why they are important. • Describe how we find minerals in the ground and how we mine them. • Analyze the environmental impact of mining.

  4. Identifying Mineral Around You • What are the walls made from? • What are the windows made from? • What is your desk made from? • What is this computer made from? • What is inside all those wires around the room? • What is all of my jewelry made from?

  5. Minerals Mineral: a naturally occurring solid that has a fixed chemical make up and set properties Nonrenewable! • Aluminum • Gold • Salt • Lead • Copper

  6. Average US person in a lifetime

  7. Ore Minerals Ore Minerals: valuable and economically extractable Gangue: no commercial value found in mineral “Waste Product” Gold Ore

  8. Pure copper Copper Ore Copper Mine in Arizona

  9. Metallic vs. Nonmetallic Metallic • Conduct electricity • Shiny • Opaque • Copper, lead, gold, silver, nickel, titanium, iron Nonmetallic • Good insulators • May be shiny or dull • May allow light to pass • Salt, clay, gypsum, silica, quartz,

  10. Sand mine Coal Mine

  11. How do they form? • Magma cooling • Evaporation • Many other ways

  12. The many ways they form…coal

  13. How are they used? (cooper as example)

  14. Copper Usage Worldwide

  15. Where in the U.S. are they found?

  16. How are they found?

  17. How are they found?

  18. Subsurface Mining Ore usually found below 50 meters • More dangerous • Some mines 2-3 miles deep • Lower impact at surface

  19. Subsurface Mining

  20. Subsurface Mining

  21. Surface Mining Ore deposits located close to surface • More land impact • “safer” • More water pollution

  22. Surface Mining

  23. Surface Mining

  24. Environmental Impacts of Surface Mining

  25. Smelting Process by which ore is melted at high temperatures to remove impurities

  26. Mineral Life Cycle

  27. Environmental Impacts of Mining

  28. Environmental Impacts of Mining: Air

  29. Environmental Impacts of Mining: Water

  30. Environmental Impacts of Mining: Wildlife

  31. Environmental Impacts of Mining: Soil

  32. Environmental Impacts of Mining: Subsidence

  33. Environmental Impacts of Mining: Underground Fires

  34. Mining Laws In the U.S. there are several laws that impact mining • Clean Water Act • Clean Air Act • Endangered Species Act • Safe Drinking Water Act • Superfund (CERCLA) • Surface Mining Control Reclamation Act

  35. Reclamation Process of restoring land to it original condition when mining is completed

  36. Review Chapter 16 Mining and Minerals • Investigate what minerals are, why they are important. • Describe how we find minerals in the ground and how we mine them. • Analyze the environmental impact of mining.

  37. How can our actions lesson impacts like this?
