13. MINERAL SUPPLY MINERAL DEMAND
MINERAL SUPPLY and DEMAND
Mineral reserves eventually will be depleted.
Import and export relationships will fluctuate
Technology often allows more access to difficult
or low grade ore deposits
Future mineral-resource shortages will occur and
cause international tension
14. MINERAL SUPPLY MINERAL DEMAND
MINERAL SUPPLY and DEMAND
Global demand is always growing
-About 2 % Pre-World War II for most metals
-About 10% World War II to Mid-1970’s
-Demand is fluctuating now
