MAIN IDEA
Modern societies depend upon a large number of a variety of
minerals. Mining of those minerals has a great impact on
our environment.

GOALS for Chapter 16 Notes
• Investigate what minerals are, why they are important.
• Describe how we find minerals in the ground and how we mine them.
• Analyze the environmental impact of mining.

Identifying Mineral Around You
• What are the walls made from?• What are the windows made from?• What is your desk made from?• What is this computer made from?• What is inside all those wires around the
room?• What is all of my jewelry made from?

Ore Minerals
Ore Minerals: valuable and economically extractable
Gangue: no commercial value found in mineral “Waste Product”
Gold Ore

Metallic vs. Nonmetallic
Metallic• Conduct electricity• Shiny• Opaque• Copper, lead, gold,
silver, nickel, titanium, iron
Nonmetallic• Good insulators• May be shiny or dull• May allow light to
pass• Salt, clay, gypsum,
silica, quartz,

Subsurface Mining
Ore usually found below 50 meters• More dangerous• Some mines 2-3 miles
deep• Lower impact at surface

Surface Mining
Ore deposits located close to surface• More land
impact• “safer”• More water
pollution
