Open-pit mining is like scooping out parts of the earth's crust, while underground mining is more about delving deep into the earth, navigating dark, narrow tunnels to reach the ore. Both methods have their challenges, but the goal is the same – to bring tungsten ore to the surface for the next stage of its journey.
