There are four main methods: underground, open surface pit, placer, and in-situ . 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 is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.read more
