Once the deposit of iron ore is feasible, the mining process is moved to digging the ore out from the earth. The most widely used technique is open-pit mining, which involves drilling and blasting the surface rock and soil to get to the ore deposit beneath it in states like Minnesota and Michigan, around the area of Lake Superior.
