How do we extract minerals? - USGS

2021-6-21  Lower grade metal ores found closer to the surface can be profitably mined using surface mining methods, which generally cost less than underground methods. Many industrial minerals are also mined this way, as these ores are usually low in value and were deposited at or near the Earth’s surface.

Mining Methods 101: How the Metals We Need Are

2016-7-6  Unfortunately for us, as the Environmental Literacy Council explains, useful minerals — from iron to gold and even the rare earth metals — rarely show up in unadulterated, large quantities that can be simply plucked from the ground and used to manufacture ovens or headphones. Instead, they generally exist as ores, or mixed collections of minerals found in rocks — and when they’re concentrated enough, it becomes economically viable to extract the metals.
