When rock ore contains small concentrations of gold, which technique is used to increase the amount of gold retrieved?

• Subsurface Mining

• Mining of near-shore sediments.

• Strip mining and mopuntaintop removal.

• Cyanide leaching of crushed rock.

• Smelting of high-grade ore.

Which of the following occurs when a mineral resource becomes scarce?

• Price increases, which can encourage use of substitiutes and resource conservation.

• Demand goes down because fewer people want to buy a mineral that is becoming rare.

• Price stays the same so the remaining minerals will be purchased quickly and mining companies can begin to mine something else.

• Mining operations are paused and, after a short time, a new supply of the mineral will become available.

• Environmental impact decreases because mining decreases when a mineral becomes scarce.
