Questions relating to Canada’s Mineral Wealth Lecture:
• What kinds of rock minerals/metals do we find here in Canada?•Where are these rocks found in Canada & why in those locations?•How valuable is mining to Canada’s economy?

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
Metallic Metallic MineralsMinerals

How Important is Mining to How Important is Mining to Canada’s Economy?Canada’s 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)
How Important is Mining to How Important is Mining to Canada’s Economy?Canada’s Economy?
Canada’s international mining trade, accounting for 19.2 percent of Canada’s domestic exports in 2009. Canada continues to be the world’s 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 productionToronto is generally viewed as the mining finance capital of the world (Toronto’s Stock Exchange has lots of mining companies on their market index).

Number of Canadians Number of Canadians working:working:
•307 000 people directly employed in mining and mineral processing– accounted for 2.1 percent of Canada’s 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.

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 mineralsUnderground 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?
