  1. Using Mineral Resources

  2. Uses of minerals • Gemstones – valued because they are rare and beautiful - used for mechanical parts and grinding

  3. Ores – minerals that contain useful substances that can be mined at a profit * Bauxite – source of aluminum * Chalcocite – source of copper * Cinnabar – source of mercury

  4. Other uses include: Materials for food Medicine Fertilizer Building materials

  5. Producing Metals From Minerals • Prospecting – searching for ore • Mining – removing ore from the ground Strip mining – machines scrape away soil to expose ore

  6. Producing Metals From Minerals Open pit mining – machines dig an enormous pit to remove ore

  7. Producing Metals From Minerals Shaft mines – miners dig shafts and tunnels to remove ores from veins

  8. Producing Metals From Minerals • Smelting – process that separates metal from ore

  9. Producing Metals From Minerals • Further processing includes: *removing impurities *creating alloys to make materials with special properties Video: coal mining
