Transcript of "Mining"

  1. 1. Welcome to Evans Mining Company<br />
  2. 2. Directions<br /> You and your mining partner must only use your toothpicks!<br />The pan in front of you is your mine!<br />Mine out the beads and seeds!<br />
  3. 3. By the way…..<br />The colored beads cost you money, the bronze & gold are worth the most!<br />
  4. 4. What it will cost you<br />You will get one piece of candy for every:<br />25 gold Beads<br />45bronze Beads<br />
  5. 5. Now…..you must get it back the same way!<br />
  6. 6. Table of Contents<br />Date: 8/17<br />Section: Minerals<br />Title: Minerals classification<br />Page 2<br />
  7. 7. Mining<br />It is the process of removing rock and mineral material from the Earth for society to use to make products!<br />
  8. 8. Open pit mining<br />(surface mining)<br />This is digging a hole on the surface of the earth to remove the material we want.<br />
  9. 9. Subsurface Mining – when the material is deep in the ground!<br />
  10. 10. Mine reclamation – returning the land to a useable state!<br />Before and after images<br />
  11. 11. II. The world of<br />minerals<br />
  12. 12. What determines if <br />something is a mineral?<br />Naturally occurring<br />solid<br />Crystal structure<br />inorganic<br />definite chemical make-up<br />
  13. 13. What do you think?<br />Which of these are minerals?<br />Sand<br />petroleum<br />gold<br />coal<br />glass<br />rubies<br />diamonds<br />water<br />Here is a hard one – What about ice?<br />
  14. 14. III. How do geologists<br />identify minerals?<br />1. One way is color!<br />http://www.minresco.com<br />http://www.prettyrock.com<br />http://www.gems-afghan.com<br />http://www.globalcrystals.com<br />
  15. 15. 2. A mineral's hardness<br />helps identify it.<br />Not all minerals have the same hardness. Some you can easily scratch with your fingernail!<br />/vwdocs/vwlessons<br />http://www.wpclipart.com<br />http://www.infowest.com<br />http://www.wpclipart.com<br />http://www.prettyrock.com<br />
  16. 16. 3. Streak test<br />Streak is the color of a mineral powder.<br /> Many minerals appear a different color when powdered than they do as a big piece. The color may be entirely different, or it may be a different shade.<br />http://cmsc.minotstateu.edu<br />http://cmsc.minotstateu.edu<br />http://www.uky.edu/KGS<br />
  17. 17. 4. Luster<br />How do these<br />look different?<br />Copyright © Dr. Richard Busch<br />Courtesy United States Geological Survey<br />Courtesy United States Geological Survey<br />Each reflects light differently – that is luster!<br />Which of these words would you use to describe these minerals?<br />Glassy, metallic, dull, silky, waxy, pearly<br />
  18. 18. 5. Minerals also <br />have different densities.<br />This means for equal size, they have their own special weight.<br />Which one is worth more?<br />How could you tell?<br />http://www.palagems.com<br />A scientist would measure their densities and they would be different!<br />The first one is topaz (worth a lot) and the second is citrine quartz (not worth a lot).<br />
  19. 19. 6. Minerals also have<br />different crystal patterns<br />Copyright © Dr. Richard Busch<br />http://webphysics.davidson.edu<br />http://www.wired-artist-jewelry.com<br />http://www.fabreminerals.com<br />Link to crystal video media player<br />quicktime<br />http://www.fabreminerals.com<br />
  20. 20. 7. Another property is the way a<br /> mineral breaks.<br />Fracture means it breaks in a random pattern that cannot be predicted.<br />Cleavage means it breaks the same way every time.<br />www.visionlearning.com <br />donsmaps.com <br />Calcite and halite break a special way.<br />Quartz and chert break in a random pattern. There is not way to predict how they break.<br />www.mrsciguy.com <br />
