How do we extract minerals? - USGS

The primary methods used to extract minerals from the ground are: Underground mining. Surface (open pit) mining. Placer mining. The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.
