Detailed explanation-2: -The method of extracting minerals from rocks buried under the Earth’s surface is called mining.
Detailed explanation-3: -The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore from the waste rock.
