T3: Mining Operations

Surface Mine

Used to extract ore and minerals close to

the surface.

Requires processsing (concentrating,

smelting, refining)

Underground Mine

Used to extract ore and minerals deeper

underground.

Requires processsing (concentrating,

smelting, refining)

Quarry

Used to obtain, gravel, dimention stone, aggregate,

sand.

No processing required though

crushing is sometimes necessary

Summary

• Key Messages– The Earth has many layers. The resources we

extract from the Earth come from the surface.– Minerals can be identified by their physical

characteristics– Rocks can be classified by the processes that

form them– There are many active mines in Manitoba– Earth processes affect the landscape and

what resources are available in an area
