· Copper mining has typically been performed through open-pit mining, where stepped benches are dug deeper and deeper into the ground over time. To remove the ore, boring machinery drills holes into the rock, and even explosives are used to break the rock apart. Globally, approximately 80% of copper production is taken from various sulfide sources.
