2020-5-7 · What are the different methods of mineral extraction? There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Find out all about it here.

Strip mining. Strip mining is the activity of removing a layer of earth to access the minerals that are in shallow deposits and continuing to do the same in adjacent areas without digging deeper vertically. Strip mining is best suited for shallow and horizontally located deposits. Strip mining activities often impacts a broader surface area.

Materials slowly accumulate via water and/or wind action and turn in a big deposit known as placer. Then the placer is collected, rinsed, and sluiced to pull out the desired minerals. This is one of the simpler methods of mining.
