What is the term for mining that involves removing mineral-bearing ore from a large surface excavation?

• A. Near-gem
• B. Open-pit mining
• C. Normal
• D. Nick (Nk)

Answer: (B)

This question tests mining terminology for how ore is removed when it’s near the surface. Removing mineral-bearing ore from a large surface excavation is called open-pit mining. In open-pit mining, large amounts of rock and soil (overburden) are removed from the surface to create a big pit, allowing access to the ore without drilling and tunneling underground. This method is economical when the ore body is spread out at or near the surface. The other terms aren’t used to describe this method. They don’t refer to the surface-pit approach, so they don’t fit the description provided. Open-pit mining is the standard term that matches “removing ore from a large surface excavation.”
