  1. Mining CGC 1D0

  2. Minerals are non-renewable resources found all over the world • The Canadian Shield is the source of many of our mineral deposits • Minerals can be divided into three groups: • Metallic (copper, nickel, uranium, gold, etc) • Fossil Fuels (coal, oil, natural gas) • Industrial (stone, diamonds, salt, potash) enriched uranium coal potash

  3. Environmental Issues • Mining can cause air pollution, acid precipitation, and can pollute local water sources • Abandoned mines can also be an environmental and aesthetic hazard

  4. Economic Issues • 50% of minerals mined in Canada are processed after being exported  Exported jobs • Global markets control mineral prices and demand • Foreign competition  lower production costs overseas make their minerals cheaper • Ghost Towns • After a mine closes up, many one industry towns have been abandoned. i.e. Elliot Lake, ON

  5. Types of Mines • Strip Mining – Used in oil sands, coal, and other minerals located near the surface. Strips are removed from the surface with machines or blasting

  6. Open Pit Mining • Used for minerals near the surface and slightly deeper. Often used for coal or rock mining. Sometimes pits can be quite deep This is in Russia!

  7. Open Pit Mining

  8. Underground Mining • Used to extract minerals deep beneath the surface using deep underground mine shafts and tunnels. Commonly used for coal or potash

  9. Underground (Shaft) Mining

  10. Underground (Shaft) Mining Wire mesh to prevent loose rocks from falling.
