Another method of copper mining is underground mining, which is used when the ore is located deep below the surface. This method involves drilling tunnels and shafts into the earth to access the ore, and it is typically used when the ore deposits are too deep or too small to be extracted using open-pit mining. Is Underground Mining Still Useful ...
