  • What are the main methods of mining? | American .

    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. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining .

    Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.
