  • 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.
