Mining
Do you have some Canadian mining products with
you today? Check your pocket for coins Are you
wearing any nylon or fleece? Do those clothes
contain zippers? What rare metallic minerals are
in your cell phones?
Mining is the process of extracting minerals from
rocks

Mining is the process of extracting minerals from
rocks naturally occurring, pure,
non-living substances found in rocks.
Minerals are divided into 3 categories in Canada
1. Metallic refined, yielding metals
2. Fossil fuels release energy when burned
3. Industrial neither metallic or fossil fuels
5
Metallic Minerals
gold bars
Copper Ore
Zinc ore

Fossil Fuels
Coal

Industrial Minerals (non-metalic minerals)
asbestos
diamonds
gypsum
salt
gravel
potash

How Important is Mining to Canadas Economy?

• Value of Minerals Produced in Canada in 2008
• Metals - 66 657 413 (or 66 billion dollars)
• Non-metals - 18 724 515 (or 18 billion
  dollars)
• Fuels - 217 701 259 ( or 217 billion dollars)
• Total of all three 455 billion dollars !
• Most valuable minerals produced
• gold,uranium (2nd in world) and nickel
  (metallic)
• Potash (1st in world), diamonds gravel
  (non-metallic)
• Oil and coal (fuel)

13
How Important is Mining to Canadas Economy?

• Canadas international mining trade, accounting
  for 19.2 percent of Canadas domestic exports in
  2009.
• Canada continues to be the worlds leader in the
  production (by volume) of potash, and it ranks in
  the top five countries for the production of
  aluminum, cobalt, molybdenum, nickel, platinum
  group metals, salt, titanium concentrate, uranium
  and zinc.
• Canada ranks second in the world in value of
  diamond production
• Toronto is generally viewed as the mining finance
  capital of the world (Torontos Stock Exchange
  has lots of mining companies on their market
  index).

Number of Canadians working

• 307 000 people directly employed in mining and
  mineral processing accounted for 2.1 percent of
  Canadas total employment
• 2009 average weekly earnings of people working
  directly in the mines processing is 1,056.
  Weekly earnings in the Canadian economy averaged
  823.

Step 3 How Do We Mine? Pg 334

• Strip Mining
• mine oil sand (bitumen), coal and other minerals
  located in the top layers near the surface
• Open Pit Mining
• mine minerals found near surface of earth, but
  also may extend deep into the ground
• Gravel, rock, diamonds, metallic minerals
• Underground Mining
• extract mineral ores vanes within earth
• Nickel in Sudbury, coal in N.S., Gold in Timmins

• Environmental controls
• -destroy habitats, clear cutting, animal
  extinction
• -develop new technologies to improve efficiency
• -by products of mining unclean
• -harmful to environment
• -global warming
• -new and improved uses of minerals
• -more uses more reasons to mine?

• Land claims of First Nations
• -who owns the land who profits?
• -Increase processing and manufacturing of
  minerals in Canada
• -boom and bust nature of mining
• -what happens to mining towns when mind closes?
