  1. MINING • BY JACKIE, CHRISTINA, MATT, AND KEEGAN Slide by: Christina

  2. WHATIS MINING? • Mining is the foundation of industrial civilization. It is the process of extracting minerals like gold, silver, copper, nickel and uranium (metallic) and salt, potash, coal and oil (nonmetallic) formations that concentrate naturally in the earth. Slide by: Christina Research by: Matt+Keegan http://www.mine.queensu.ca/Department/What-is-mining.html

  3. CANADA’S MAJOR MINERALS MINED • Metallic Minerals, Fossil Fuels, and Industrial Minerals Used to make tools, planes (anything metal) for gas for cars, planes, heating homes, medicines, plastics. used for things such as glass, paint, ceramic tiles. Slide by: Christina Research by: Matt+Keegan

  4. What are they used for? • Metallic Minerals: Used for jewelry products such as rings, necklaces, and bracelets. • Fossil Fuels: Used for things such as gasoline to fuel cars, trucks, lawnmowers etc. • Industrial Minerals: Used for products such as gravel and salt. Slide by: Matt Research by: Matt+Keegan

  5. Metallic Metals Industrial Metals Fossil Fuels TOP THREE PROVINCES WHERE MINERALS ARE FOUND Nunavut North West Territories Quebec British Columbia P.E.I Alberta Ontario New Brunswick Nova Scotia Slide by: Christina Research by: Matt+Keegan

  6. HOW ARE MINERALS FORMED? • Minerals are found in the earth or are naturally occurring substances. They are found in dirt, rocks, and water. • They are not made by man. • Minerals are also found in mines such as an open pit mine, underground or tunnel mine, quarry, dump, or alluvial deposit. Slide by: Christina Research by: Matt and Keegan

  7. Rock Cycle Slide by: Christina

  8. Slide by: Christina Picture by: Keegan Research by: Matt+Keegan More on types of Mining • Drift – Mining horizontal and upwards so the minerals fall down and are easier to mine but more dangerous • Shaft – Mining vertically down, used to mine extremely far down into the earth • Open Pit – Mining a large open space when the ore is just underneath the surface • Slope - Mining down on an angle where more branches of mines can be added

  9. Types of mining • There are 2 types of mining, STRIP MINING and UNDERGROUND MINING • Strip mining is when you don’t need to dig very far under the earths surface to mine minerals • Underground mining is the opposite. Where minerals are found farther underground • There are 5 different types of both underground and strip mining but there are 4 commonly used types of mining Slide by: Christina Research by: Matt+Keegan

  10. Surface Mining Steps • 1. Overburden (trees, rock, earth) is removed. • 2. Blasting may be necessary to remove some mineral deposits. • 3. Material is loaded to dragline to pick up loose material on the ground, • 4. Material is taken to storage area to await processing in the mill or shipment to market. Slide by: Matt Research By: Matt

  11. Mine Blasting • In mines,there are large amounts of rock and dirt in the way. When the rock and dirt is too big for machinery to move it, miners use T.N.T to blast through the rock and dirt. These blast allows miners access to the minerals they want to mine. • (Mine Blast Video) Slide by: Matt Research by: Matt

  12. Strip Mining Photos Slide by: Matt

  13. Underground Mining Steps • 1. Miners take elevators down to the mines. • 2. Holes are drilled in the rock face and filled with explosives. • 3. Explosives are set off. • 4. Miners remove blasted rock. • 5. The ore is then taken to a storage site to await processing. Slide by: Matt Research by: Matt

  14. Underground Mining Photos Slide by: Matt

  15. Chilean Miners • In August of 2010, 33 Chilean Miners were trapped underground while mining. An explosion that collapsed tons of rocks and dirt on them left them stranded underground. The miners were all rescued 69 days later by a small elevator shaft that brought one miner up at a time. Mining is a very dangerous job that requires intense focus and experience. Slide by: Matt Research by: Matt

  16. Photos of Chilean Miners Slide by: Matt

  17. Canada’s Mining in Panama • Canadian Mining companies are taking over Panama’s lush rainforest to mine for rare and precious minerals. These mining companies are destroying habitats and taking down the culture of Panama. Mining companies are getting too greedy today and always want a bang for their buck. Slide by: Matt Research by: Matt

  18. Panama’s Rainforest Slide by: Matt

  19. Canadian Mining Companies • Barrick Gold, Teck Resources Ltd. , Inmet Mining Corporation. These are the top 3 mining companies in Canada and mine the most minerals making them the most sustainable. Slide by: Matt Research by: Matt

  20. Canada’s Mining Industry Threatened • Nothing lasts forever on earth. In the mining industry it is the same. Minerals and resources will eventually run out. • Mining wastes a lot of land and destroys the land. • Mining costs a lot of money. Slide by: Matt Research by: Matt

  21. Elliot Lake Slide by: Keegan Research by: Keegan • Elliot lake was once a community where most the populations jobs revolved around their mining industry • In the 1950s a large deposit of uranium was found and supplied most of the worlds uranium for sometime. But this uranium was eventually excavated completely • In 1995 Elliot Lake became a community for those in rehabilitation and retired to people to live because of its beautiful area

  22. Key Word Answers • Mineral– a naturally occurring substance that is solid and stable at room temperature, representable by a chemical formula, usually biogenic, and has an ordered atomic structure • Metallic Mineral - Minerals that produce metal when it’s extracted from its ore. Ex: iron, gold, silver, uranium • Fossil Fuel – Natural fuels made from the remainders of living organisms formed millions or years ago • Industrial Mineral - Geological materials which are mined for their commercial value, which are not fuel and are not sources of metals! They are used in their natural state or either as raw materials Slide by: Christina+Jackie Research by: all

  23. ..CONTINUATION KEYWORDS • Mineral Reserve - Mineral resource classification is the classification of mineral deposits based on their geologic certainty and economic value • Geologist - Scientists who study who study the history, composition and structure of the earth • Ore - Natural materials taken from the ground. Expensive metals and minerals can be removed from ores • Strip Mining -the mining of ore or coal from an open mine. A type of surface mining Slide by: Christina Research by:alll

  24. ..CONTINUATION OF KEYWORDS • Open Pit Mining - is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow • Underground Mining - refers to a group of underground mining techniques used to extract coal, oil shale and other minerals or geological materials from sedimentary rock • Milling - removing rock and other substances from ores in order to purify it • Smelting - Smelting is when metals or minerals are taken from its ore by a heating and melting procedure Slide by: Christina+Jackie Research by:all
