Transcript of MINING
-Industrial (Non-metallic) Minerals
So how can Canada's mining industry improve?
Looking for Metallic Minerals
Metallic minerals are found in igneous and metamorphic rocks of the Canadian Shield and other regions of Canada. There are a few tactics for finding minerals.
-Canada is third in the world for mineral production
-Canada is the largest exporter of minerals
We export 80% of the minerals we produce and find because we have too much for our small population.
-The total production cost in Canada in 2004 was $24.2 billion
-Mining has helped Canada rebuild their railroads since World War II for the transportation of minerals throughout Canada
-The government strongly funds the mining industry and are constantly looking for new methods and procedures for mining
-Metallic Minerals are minerals that when refined are metals
-Metals, such as gold, silver, and platinum, are valued for their rareness and beauty.

Magnetic field produced from ore bodies is detected by a magnetometer.
Igneous and metamorphic rocks
Another instrument called Geiger counter is all used to detect radioactive minerals.

Decisions, Decisions! Spend millions of dollars on developing
a mine that may be very profitable? Or play it safe as if the
ore bodies aren't valuable and large enough, the company
most likely goes out of business!
Rock samples for analysis, soil tests for chemical erosion from nearby ore bodies, and satellite images to show geologic structure of an area.
-For the last 200 years fossil fuels have been burned to provide energy for our modern nation.
-Over the last century scientists have found more uses for these fossil fuels
-They include oil, gas, coal etc.
Industrial (non metallic) Minerals
Mining has caused many issues, the most serious concern is the effect mining has on our environment
Abandoned Mines: many mines across Canada were abandoned after the ore ran out.
One-industry Towns: Some towns are dependent on the mining industry so if a mine closes down or runs out then that town will start to die off
Acid Precipitation: mine smelters are one of the worst pollutants that cause acid precipitation. Acid rain is caused by emissions from processing plants, which react with the water molecules in the atmosphere to produce acids
Some of the Mining Industry's Challenges are;
-All things that are mined that aren't metallic minerals or fossil fuels
-examples of industrial minerals are Asbestos, Soapstone and Diamond
Challenges for the Mining Industry
Mining Metallic Minerals
Finding Valuable Minerals
Importance of mining in Canada
Canadian companies should adjust to international competition and pricing.
Consider environmental protection, balance amounts of mines and natural areas.
Canadian mining companies should develop new technologies that will their operations as efficient as possible!
Better uses for minerals should be found.
Mining towns should be assisted in developing a mew economic base.
Step 1: Send the ore to the the factory where they strip the stones from the valuable metals dumping the residue in a tailing.
Step 2: Use chemicals to erode the stone and get as much pure metal as possible.
Step 3: Smelt the metal, separate the slag and send the metal to the milling machine.
Step 4: Use the milling machine to create the ingots
Processing Metallic Minerals
Two types of spots
Mineral Deposit: There is minerals near, but not worth to mine it
Mineral Reserve: There is a lot of minerals in one area that is worth mining.
Most mining areas aren't near any transportation routes. Due to this factor, companies have to pay more for new roads, mining factories along with water and other resources moved over there.
3 Ways of Mining
Take off a few layer
from the surface
Blow off 10-15M deep of minerals, and mine what is there.
Dig deep into the Earth, to get the minerals that are valuable.
Use of elevators to transport people and minerals to and from the surface
