Copper ore is typically mined through two primary methods: open-pit mining or underground mining. In open-pit mining, large pits are dug into the earth using heavy machinery, and the ore is extracted from the rock. Underground mining, on the other hand, involves tunneling into the earth to reach the copper deposits. 2.
