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
